1 SCOPE

1.1 Identification This Interface Design Document (IDD) applies to the Special Sensor Microwave Imager/Sounder (SSMIS) Ground Processing Software (GPS) Computer Software Configuration Item (CSCI) D93000Y. The SSMIS CSCI is specified in the Software Requirements Specification (SRS) S-DMSP-881.

1.2 System Overview Figure 1 shows the SSMIS scan geometry. The system scans at a constant 45-degree angle from nadir and intersects the Earth’s surface at a constant incidence angle of 53.1 degrees. Radiometric data from the 24 channels is collected along an active scan angle of 144 degrees across track producing a swath width on the ground of 1707 kilometers. The sensor collects data to the aft of nadir for a morning ascending node spacecraft orbit, and collects data forward of nadir for a morning descending node spacecraft orbit.

Figure 2 shows a simplified block diagram of the SSMIS system. The SSMIS collects microwave energy from the Earth’s surface and atmosphere with a rotating 24-inch parabolic reflector. This reflector focuses the energy on an assembly consisting of six feedhorns, which provide the initial frequency multiplexing for the 24 channels. The reflector and the six feedhorns rotate with the entire sensor canister. Rotation is accomplished by the scan drive subsystem consisting of a scan drive assembly (part of the sensor) and Scan Drive Electronics (isolated from the sensor).

Located at the top of the canister are a cold calibration reflector and a warm calibration source, which do not rotate with the canister. The feedhorns view a fixed cold calibration reflector and a fixed warm calibration source for each revolution of the sensor. These calibration data are used to convert the sensor output to absolute radiometric brightness temperatures.

The feedhorn data are input to the receiver subsystem where frequency multiplexing occurs to produce 24 channels of data. The receiver outputs are converted to the video spectrum, digitized and formatted, and sent to the Operational Linescan System (OLS) under control of the sensor signal processor and the flight software. The SSMIS data is transmitted to the ground by the OLS. Ground processing is performed at Air Force Weather Agency (AFWA) and Fleet Numerical Meteorological Oceanography Center (FNMOC) to process the sensor data into calibrated and Earth-located sensor data records (SDRs) and finally into a variety of environmental data records (EDRs).

1.3 Document Overview The purpose of this document is to define the interface elements between SSMIS GPS CSCI and the external operating environment, as defined in the Interface Requirements Specifications (IRS) S-DMSP-884. The SSMIS GPS has one CSCI and the interfaces are files and databases. This IDD contains the following information as required:

3 INTERFACE DESIGN External interfaces are data files that are shared by other program users. These interfaces are: (a) Raw Sensor Data Records (RSDRs) - Raw satellite sensor data needed as input (b) Ephemeris - Ephemeris is inserted in the RSDR file and is used for location algorithms. (c) Process Control - provided by NGES and then maintained by the sites using a text editor. These are

default user-specified processing capabilities and associated parameters for normal SSMIS processing for each of the Computer Software Components (CSCs), and one read by all CSCs.

(d) Data Files - External data files will be provided by NGES. These data files are accessed by the GPS for imager/sounder processing.

The SSMIS CSCI is composed of six Computer Software Components (CSCs): Sensor Data Records Processor (SDRP), Environmental Data Records Processor (EDRP), GRID Processor (GRID), Verification Processor (VERP), Update Processor (UPDP), and Early-Orbit/State-of-Health (EOSOH). Each of these CSCs is documented in Report 11846, Software Design Document. Figure 3 depicts the interfaces to the SSMIS GPS.

3.2 24 Hour Summary File (24SUM)

Created By : SDRP, EDRP, GRID, VERP, or UPDP

Used By : User

Format : ASCII, formatted, sequential

Description : This file consists of daily summary processing information by the SDRP, EDRP, GRID, VERP, and UPDP processors. Each processor will output the CSC name, start time, stop time, satellite ID code, status of processing, number of warnings, and other summary information.

If the 24-Hour Summary File does not initially exist, a processor will create the file. Otherwise, the processor will append the summary information to the end of the file. When the file is created, the current date is appended to the input 24-Hour Summary filename so that a new file is created every day.

3.9 A Priori Parameter Data Water Vapor Mass File (APDWVM)

Created By : User

Used By : UPDP


Description : This file contains a priori matrices of water vapor mass parameter versus channel covariance coefficients (Parm-Data matrices) and expected water vapor mass parameter vectors. The matrices are combined with the humidity channel alpha-beta coefficients for application in algorithms to compute updated Water Vapor Mass D-Matrices. Expected parameter vectors are applied in algorithms to compute Augmented Water Vapor Mass Vectors.

3.12 Cloud Database File (CLDDAT)

Created By : Site

Used By : EDRP, VERP


Description : This file consists of a 4-layer cloud data that is generated from the AFWA Nephanalysis program (NEPH). The data is referenced by latitude (-90..90 + north) and longitude (0..360 + east). Site specific (SiteLib) routines are used to load the data into memory and retrieve the data. See the SiteLib Interface Design Document for interface details.

3.13 Constants File (CONSTANTS)

Created By : User

Used By : SDRP, EDRP, GRID, VERP, UPDP, EOSOH, SIM


Description : This file can be edited by the user and is read by the CSCs. This file contains constants common to all CSCs and also those unique to each CSC. The file begins with a prolog to capture the revision history of the file. Next, the global constant section is shared by all CSCs and begins with the label GLOB and ends with GLOEND. The other sections are only read by the relevant CSC and begin with a label for the CSC name (e.g., SDRP, EDRP, VERP, & UPDP [Note: GRID makes use of constants in the GLOB section only]) and end with a label (yyyEND) where yyy = SDR, EDR, VER, UPD, or EOS.

The user may add comments in this file subject to the following rules:

1. The first six characters on a comment line should be “#” (i.e. 6 “#” characters). This prevents any confusion between data labels and comments.

2. Comment lines and data lines cannot occur on the same line.

3. Comments should not occur between a data label and its associated data lines. Data labels occur in the first 6 columns of the file and are used as search tokens to find the data. The data lines should occur on the same line, or immediately on the next line.

4. Comments should not occur between multiple data lines for a specific data item. NOTE: The prior Rev3 release and prior releases are not compatible with this version of the constants file. The exact contents, acceptable values, and instructions on how to make changes are documented in the Software User's Manual.

Note: Because the EOSOH is run independently of the SDRP, EDRP, GRID, VERP, or UPDP, a separate version of the constants file that contains the constants needed by the EOSOH, is located in the file directory where the EOSOH is executed.

For the GPS, there is a separate constants file for each sensor 1-5. For the EOSOH constants file, data for all five sensors is contained in one constants file.

Current Data Record 5640 The header record contains dates and times of the first execution of VERP since the statistics were reset, and the number of executions of VERP. Data Records are stored in the order by item, atmospheric type, D-Matrix status, cloud status, and then category for lower data. For upper air data, the order of records follows item, error band, alpha-beta status, and then category. ---------------------------------------------------------------------------- # #atm D-Matrix cloud total rec category items types status status ---------------------------------------------------------------------------- 5 * 3 * 2 * 3 = 90 Temp Brightness Channels 9 * 25 * 2 * 3 = 1350 Humid Brightness Channels 6 * 25 * 2 * 3 = 900 Relative Humidity 6 * 25 * 2 * 3 = 900 Specific Humidity 8 * 25 * 2 * 3 = 1200 Water Vapor Mass 15 * 3 * 2 * 3 = 270 Temperature 15 * 3 * 2 * 3 = 270 Heights 14 * 3 * 2 * 3 = 252 Thicknesses 1 * 3 * 2 * 3 = 18 Tropopause Pressure 1 * 3 * 2 * 3 = 18 Tropopause Temperature ---------------------------------------------------------------------------- 5268 records for Lower statistics ---------------------------------------------------------------------------- # #error alpha beta total rec category items bands status ---------------------------------------------------------------------------- 6 * 3 * 2 = 36 Upper Brightness Channels 8 * 3 * 2 = 48 Upper Temperatures 8 * 3 * 2 = 48 Upper Thicknesses 9 * 3 * 2 = 54 Upper Heights ---------------------------------------------------------------------------- 186 records for Upper statistics ---------------------------------------------------------------------------- # #atm D-Matrix cloud total rec category items types status status

3.15 DCDM Pairs File (DCDMPR)

Created By : VERP

Used By : VERP, UPDP


Description : This file contains computed and measured data vector values. It contains raw data from which channel statistics are computed. These channel statistics are analyzed to evaluate measured channel versus computed channel data. The "data computed" (DC) value is computed from a matching RAOB. The "data measured" (DM) value is computed from the satellite data. VERP appends to the end of the DCDM Pairs File. The UPDP reads the DCDM Pairs file and then deletes the DCDM Pairs data from the file.

The channel numbers in the file correspond to the SSMIS channel numbers except for 25, 32,33, and 34. Channel 25 is the same as channel 24 except as used for upper air sounding. Channels 32, 33, and 34 are the same as channels 2,3, and 4 except as used for temperature instead of humidity.

3.20 Environmental Parameter Inversion Coefficients File (EPIC)

Created By : User

Used By : EDRP (Due to algorithm changes, most of the data in this file is read, but is no longer actually used by the EDRP. The file is retained as a placeholder to avoid changes to existing run scripts.)

The only data currently used by the EDRP are the coefficients for computing snow water content using the Kunzi algorithm.

3.21 Geomagnetic Database File (GEOMAG)

Created By : NGES

Used By : SDRP

Format : Binary, unformatted, direct

Description : This file contains the vectors for the geomagnetic field strength around the world. The data is stored as X,Y, and Z components and is referenced by latitude (-90..90 + north) and longitude (0..360 + east). The geomagnetic field strength is used in upper air sounding algorithms.

The data file is generated by using International Geomagnetic Reference Field (IGRF) coefficients and interpolating for the appropriate years.

The geomagnetic files are not tied to the launch date, but to the current calendar date. These files are based on coefficients that are updated every 5 years. (See http://www.ngdc.noaa.gov/IAGA/vmod/igrf.html). For the best accuracy the geomagnetic file modeled for whatever the current year is should be used. Files are provided to year 2010 in 6-month increments. These files may be found on the CD-ROM in the SSMIS/DATAFILES directory. Examples of such files are geomag_2001.db, geomag_2001.5.db, geomag_2001_le.db, geomag_2001.5_le.db, … geomag_2010.db. Those with “_le” in the name refer to little endian versions. It is recommended that one copies a specific name to generic name. For example, if the launch is in first half of 2003 then copy geomag_2003.db to the generic name geomag.db. If the launch is in the 2nd half of 2003 then copy geomag_2003.5.db to the generic name geomag.db. And copy in a similar way for other years (as the calendar date changes).

BY Y component of the magnetic field in earth centered coordinates



BZ Z component of the magnetic field in earth centered coordinates



3.21.2 File Format The Geomagnetic DB file is logically represented as a two-dimensional table of 287 rows x 576 columns. Row 1 represents latitude near 90 degrees, and Row 287 represents latitude near -90 degrees (+ north). Column 1 represents longitude near 0 degrees and column 576 represents longitude near 359 degrees (+ east). This table size is equivalent to a resolution of 0.625 degrees over the world. An entry in the table consists of 6 bytes. The 6 bytes represent an array of three 2-byte integers. This array contains the X, Y, and Z component of the magnetic field for a given latitude and longitude.


66

It should be noted that the end of the file requires padding with zeroes such that the total file size is an even multiple of 512 bytes. The ground software reads all binary files in 512-byte blocks. Thus, the size of this file should be 576 columns x 287 rows by 6 bytes = 991872 bytes. This is 1937.25 blocks, so we must add a pad of 384 bytes to get an even multiple of blocks - 1938 in total.

3.37 Operational Temperature D-Matrix File (ODMTEM)

Created By : User (Proposed Temperature D-Matrix can be copied to the Operational Temperature D-Matrix)

Used By : EDRP, UDPD


Description : This file contains Operational Temperature D-Matrix and augmented parameter vectors for atmospheric types 26-28. If updates to Lower-Air temperature channels are required, these coefficients are read in, updated as necessary, and written by UPDP to the Proposed Temperature D-Matrix file. The user can then copy the Proposed Temperature D-Matrix as the Operational Temperature D-Matrix. EDRP reads and processes coefficients from the Operational Temperature D-Matrix file to compute various sounding parameters. Each satellite may have its own specific D-Matrix.

The D-Matrix contains coefficients for 3 different atmospheric types listed below

Atmospheric type 26 - Tropopause pressure category 1 ( P < 120 mb) Atmospheric type 27 - Tropopause pressure category 2 ( 120 <= P <= 250 mb) Atmospheric type 28 - Tropopause pressure category 3 (P > 250 mb)

3.44 Saved RAOB File (SAVRAO)

Created By : VERP

Used By : VERP


Description : This file contains the upper verification records with the saved RAOB data record that has been matched by distance and time. A saved RAOB data record is appended to the end of each upper verification record. This file is used by VERP to save upper verification records with their matching RAOBs when a matching ROCOB could not be found during the current execution of VERP. The saving of the data allows for matching to ROCOBs that are entered into the site's Vertical Profile database at a later time.


The Saved RAOB File header data is identical to the Upper Verification File header data record. However, the File ID is 13. 3.44.1.2 Upper Verification Scene Data

Scan Header 2 : : The Revolution Header specifies the number of Scan Headers in the file. Each Scan Header specifies a number of imager, environmental, LAS, and UAS scans, and the number of scenes in each scan. The format of the odd and even environmental scenes are different, depending on whether the environmental scan is odd or even. 3.45.2.1 Revolution Header 1 32 bits Byte# -------------------------------------------------------------------------- 1-4 | File Info Word | | Software Rev # | Endian Status | File ID (=1) | |------------------------------------------------------------------------| 5-8 | Revolution number | |------------------------------------------------------------------------| 9-12 | Year | |------------------------------------------------------------------------| 13-16 | Julian day | Hour | Minute | |------------------------------------------------------------------------| 17-20 | Satellite id | Number of SDR Records | |------------------------------------------------------------------------| 21-24 | ASCII Constants File Identifier |Proc.Stat.flags | |------------------------------------------------------------------------| 25-28 | Constants File Checksum | Processing Status Flags 2 | -------------------------------------------------------------------------- 29-40 | Spare (3) | --------------------------------------------------------------------------

Processing Status Flags, also described as the processing option flags, describe the processing state for key algorithms used to generate the SDRs. On the SUN machine those options are ordered as follows: The first bit (bit 0) represents warm load bias processing status (0=off/1=on). The second bit (bit 1) represents the residual Doppler processing status (0=off/1=on). The third bit (bit 2) represents the scan non-uniformity processing status (0=off/1=on). The fourth bit (bit 3) represents the cross polarization & spillover correction if the value is (0), but if the value is (1) it represents the antenna pattern correction (1). The fifth bit (bit 4) represents the Backus-Gilbert re-sampling of channels 12-14 to the channel 15-16 grid (0=off/1=on). The sixth bit (bit 5) represents the calibration data averaging [re-averaging if one considers the initial averaging done by the flight software aboard the sensor] (0=off/1=on). The seventh bit (bit 6) represents the Moon Intrusion repair (0=off/1=on). The eighth bit (bit 7) represents the calibration data spike repair (0=off/1=on).

Processing Status Flags 2 is a continuation of the above processing status flags. The Sun Intrusion processing status is defined in the first through third bits (bits 0-2). The combination of the three bits is used to define the processing option which may be 0 through 5. The 16th bit (bit 15) represents the output resolution of environmental channels 12-16-‘0’ indicates the old format of 1/10th degree and ‘1’ indicates the new format as of Rev 6.0 of 1/100th degree. The 4th through 15th bits (bits 3-14) are spares. Because the SDR scan header is packed starting at the beginning of a 512-byte block, the SDR revolution header is actually 512 bytes in size despite not being depicted as such. This means that there is enough room for an additional 472 bytes of data in the revolution header without changing the overall SDR file format.


142

3.45.2.2 Scan Header Note: Scan Headers are written to the SDR file on 512 byte boundaries. Thus, after the UAS scenes have been written for the previous Scan Header, the next Scan Header will begin on the first byte after a byte number that is divisible by 512. For example, to find the byte number of the next scan header from the end of the previous scan's UAS scene data, the following formula can be used: The next Scan Header will start at the first byte # (512 * n) + 1 that occurs at or after the current write position. 1 32-bits Byte# |------------------------------------------------------------------------| 1-4 | SDR Sync word | |------------------------------------------------------------------------| 5-8 | Year | |------------------------------------------------------------------------| 9-12 | Julian day | Hour | Minute | |------------------------------------------------------------------------| 13-16 | Scan number | |------------------------------------------------------------------------| 17-20 | #imager scans | #enviro scans | #LAS scans | #UAS scans | |------------------------------------------------------------------------| 21-24 | Imager start scan time (scan 1) | |------------------------------------------------------------------------| 25-28 | Imager start scan time (scan 2) | : : |------------------------------------------------------------------------| 129-132 | Imager start scan time (scan 28) | |------------------------------------------------------------------------| 133-136 | scan 1 #I.S. | scan 2 #I.S. | scan 3 #I.S. | scan 4 #I.S. | |------------------------------------------------------------------------| 137-140 | scan 5 #I.S. | scan 6 #I.S. | scan 7 #I.S. | scan 8 #I.S. | |------------------------------------------------------------------------| 141-144 | scan 9 #I.S. | scan 10 #I.S. | scan 11 #I.S. | scan 12 #I.S. | |------------------------------------------------------------------------| 145-148 | scan 13 #I.S. | scan 14 #I.S. | scan 15 #I.S. | scan 16 #I.S. | |------------------------------------------------------------------------| 149-152 | scan 17 #I.S. | scan 18 #I.S. | scan 19 #I.S. | scan 20 #I.S. | |------------------------------------------------------------------------| 153-156 | scan 21 #I.S. | scan 22 #I.S. | scan 23 #I.S. | scan 24 #I.S. | |------------------------------------------------------------------------| 157-160 | scan 25 #I.S. | scan 26 #I.S. | scan 27 #I.S. | scan 28 #I.S. | |------------------------------------------------------------------------| 161-164 | Environmental start scan time (scan 1) | |------------------------------------------------------------------------| 165-168 | Environmental start scan time (scan 2) | : : |------------------------------------------------------------------------| 253-256 | Environmental start scan time (scan 24) | |------------------------------------------------------------------------| 257-260 | scan 1 #E.S. | scan 2 #E.S. | scan 3 #E.S. | scan 4 #E.S. | |------------------------------------------------------------------------| 261-264 | scan 5 #E.S. | scan 6 #E.S. | scan 7 #E.S. | scan 8 #E.S. | |------------------------------------------------------------------------| 265-268 | scan 9 #E.S. | scan 10 #E.S. | scan 11 #E.S. | scan 12 #E.S. | |------------------------------------------------------------------------| 269-272 | scan 13 #E.S. | scan 14 #E.S. | scan 15 #E.S. | scan 16 #E.S. | |------------------------------------------------------------------------| 273-276 | scan 17 #E.S. | scan 18 #E.S. | scan 19 #E.S. | scan 20 #E.S. | |------------------------------------------------------------------------| 277-280 | scan 21 #E.S. | scan 22 #E.S. | scan 23 #E.S. | scan 24 #E.S. | |------------------------------------------------------------------------| 281-284 | LAS start scan time (scan 1) | |------------------------------------------------------------------------| 285-288 | LAS start scan time (scan 2) | |------------------------------------------------------------------------|

3.46 SDRP Diagnostics File, Auxiliary Warm and Cold Calibration Data

Created By : SDRP

Used By : User

Format : ASCII, formatted (comma delimited), sequential. Due to the number of data columns this data is best reviewed via MS Excel or a similar utility.

Description : This file is output by SDRP and is an auxiliary file not specified in the run script. The name of the file is the same as that of the SDRDIA file with the exception that the DIAG suffix is replaced with CAL. It contains warm and cold calibration data (counts) as down-linked by the flight software (raw) and smoothed from spike removal, sun intrusion removal, moon intrusion removal, and the calibration data re-averaging. Note that values for dropout scans will be found in this file although no scans actually exist in SDR or TDR files. This is due to the nature and needs of the fast Fourier transform. The output is documented in the Software User's Manual.

3.57 Surface Tag Data File (SURTAG)

Created By : FNMOC

Used By : SDRP


Description : This file contains the surface tag values for the surface types around the world. This file is used to determine the surface type at a given latitude and longitude. The surface tag data file and supporting routines were provided to NGES by FNMOC.

3.57.2 File Format The Surface Tag Data File is physically formatted as a binary direct access file of 2560 byte records. The first 3 records (bytes 1-7680) contain data for a low-resolution table and the remaining records are for a high-resolution table. Physically, the low-resolution data is stored in latitude priority order. For example, the first surface tag is for latitude near -90 and longitude near 0.0 degrees. Subsequent data is for increasing latitude to near 90 degrees (the following 18 32-bit words). The next set of 18 words will begin for latitude near -90 again, but for longitude near 5.0 degrees. 1 32-bits Byte# -------------------------------------------------------------------------- 1-4 | Surface Tag or Byte Address | Surface Tag or Byte Address | |------------------------------------------------------------------------| 5-8 | Surface Tag or Byte Address | Surface Tag or Byte Address | |------------------------------------------------------------------------| : | Surface Tag or Byte Address | Surface Tag or Byte Address | |------------------------------------------------------------------------| : : : : : : |------------------------------------------------------------------------|

Logically, the low-resolution table is represented as a two-dimensional table of 36 rows x 72 columns. Row 1 represents latitude near -90 degrees, and Row 36 represents latitude near 90 degrees (Logically, the data convention is latitude + north, longitude + east, but data is physically stored with the latitudes in reverse order.). Column 1 represents longitude near 0 degrees and column 72 represents longitude near 359 degrees. This table size is equivalent to a resolution of 5.0 degrees over the world. An entry in the low-resolution table consists of a 2-byte integer. If the integer value is negative, then the table entry is the negative of the surface tag value. If the integer is positive, the value is a pointer to a high-resolution table of surface tags.

3.58 Temperature Data Record File (TDR)

Created By : SDRP

Used By : User


Description : This file contains earth-located sets of antenna temperatures that have been surface tagged, calibrated, and averaged. Calibration means that the counts have been converted to temperatures using asymmetric flight software averaged cold and warm calibration counts. The calibration counts are an average of four measurements per scan and eight scans for a total of 32 measurements. A given scan therefore receives values averaged for the current and previous seven scans—thus asymmetric. There are no further adjustments to the antenna temperatures. The averaging that has been done to the antenna temperatures has been done in the flight software along scan and not in the direction of the ground track. Thus, there are antenna temperatures for every channel for every good scan.

Processing Status Flags, also described as the processing option flags) describe the processing state for key algorithms used to generate the SDRs. On the SUN machine those options are ordered as follows: The first bit represents warm load bias processing status (0=off/1=on). The second bit represents the residual Doppler processing status (0=off/1=on). The third bit represents the scan non-uniformity processing status (0=off/1=on). The fourth bit represents the cross polarization & spillover correction if the value is (0), but if the value is (1) it represents the antenna pattern correction (1). The fifth bit represents the Backus-Gilbert re-sampling of channels 12-14 to the channel 15-16 grid (0=off/1=on). The sixth bit represents the calibration data averaging [re-averaging if one considers the initial averaging done by the flight software aboard the sensor] (0=off/1=on). The seventh bit represents the Moon Intrusion repair (0=off/1=on). The eighth bit represents the calibration data spike repair (0=off/1=on).

Processing Status Flags 2 is a continuation of the above processing status flags. The Sun Intrusion is processing status is defined in the first through third bits. The combination of the three bits is used to define the processing option which may be 0 through 5. The remaining 13 bits are spares.
