INTRODUCTION

The objective of Project OPAQUE was to gather continuous data from a series

of measurements in the visible and infrared regions over a period of several

years. This requirement for the continuous data recording of the various

experiments has resulted in a large data base that must be studied. Concurrent

with the management of the data base was the requirement of maintaining the

central data logger system and the changes to the control programs to ,i[,:,txtfIdat(

the insertion and removal of the various measurement sensors at the West Germany

field site.

This report describes all of the additional control programs and procedures

that have been developed during this contract period to generate, edit, process,

and analyze the digital data tapes during the Post-OPAQUE phase and is divided

into two parts. Part I of this report describes the raw data tape analysis and

cataloging procedures along with the sensor performance and analysis studies.

Part II describes the additional programs that have been developed to produce

data tapes containing selected sensor data, the generation of additional data

tapes in the OPAQUE data hank format, and the additions to the data tape

catalogues.

The program design objectives developed during previous efforts1'2 on this

task have been retained and refined in the development of the additional

programs described herein. The use of a standard control language in the

program design has proven invaluable in that extensive modifications have been

made to the program packages without a major rewrite of the programs. Fxtensive

use was made of procedure files to link the necessary programs to perform

soecific tasks, and thereby simplify their use in the analysis and production of

the various data files along with increasing the cost effectiveness of each

computer job execution.

PART I. RAW DATA TAPE PROCESSING PROCEDURES.

1.1 EXPERIMENT SAMPLING SEQUENCES

Due to the changing experimental requirements, the data channel assignments

and sampling rates have undergone a number of revisions over the past three

years. Table 1. The Data Channel Assignments, given below reflects the changes

in the experimental data values sampled and recorded, along with th, various

sampling rates programmed for each data channel. It should be noted that the

data channel numbers are in octal (base 8) which accounts for the fact that

channels 8,9,18,19,28,29,38, and 39 do not appear in the table. Each data

channel has two discrete digits assigned to it which are used to record filter

positions, gain steps, etc. The unused discrete data digits on several of the

data channels are used to record the digital output of the sun sensor, the

digital rain gauge, and the ceiling meter. The mnemonics listed in the table

are derived in most cases from the instrument names and are used to identify the

data in the HISTOGRAM and DATA PROFILE plots.

Each data channel is formatted and recorded as a 36-bit string, grouped as 9

hexadecimal digits. The interpretation of these 36-bit strings is as follows:

Another use of thp Raw Data Tape Directories is in determining tho

percentaqr- of data logger system half-day 'off-line?' time on a monthly or yearly

basis. Viewed in this way, and usino Decembpr, 1976 as the startina month for

the OPAQUE measurement program, Table 10 below summarizes both monthly and

yearly perfurmance throuoh the staLion close-dnwn in April 1983.

A diailed analysis of the data logger recording time on an hourly or minut(

basis can be carried nut using the data tape timing information contained in the

syste. fi!,, FAPEFTIE (the new raw data tape log file).

(onsidering the fact that the data logger system was nperated continuously

in an unattended mode, the yearly percentage of "down-time" is quite remarkable 7

For the totil period of operation given above. The majority of the daily

outaqos can be attributed to losses of power at the field site and reachino an.

end of tape condition on the magnetic tape recorder. The remaining outages can

he attributed to periods of hardware maintenance or system software and hardware.

high sample rate channels, the data tape can last beyond 20 days, depending on

the data channels disabled. Prior to 1980, the disabling of the sampling of the

Scanning Nephelometer (data channels sampled every second for thirty minutes on

alternate hours) is clearly visible in the tape "life" starting in June, 1977.

The changing of the Luxmeter sampling from every 4 seconds, continuously to a

sampling rate of once a minute, continuous, is evident in April, 1980 and later.

The progressively long tape life through the years 1980, 1981, and 1982 and 1983

is due to the disabling of inactive data channels by the station operator as

various instruments were removed from service.

1.2 OPAQUE RAW DATA TAPE LIBRARY.

As the raw data tapes are received by the University of Lowell research

team, they are cataloged manually in the tape lop jnd entered into the system

file, TAPEFILE, givino the starting and ending day-of-year, hour, and minute for

each continuous data recording. Currently there are 450 raw data tapes

cataloged, a data base representino seven years of essentially continuous. OPAQUF

me, asurements. The need for maintaining this raw tape data base has been

Oemonstrated many tires where the raw tape must be rerun to create riew working

files to replace those lost due to tape mounting problems, or computer system

errors.

To assist in locating the raw data tape(s) for a given period of time, or to

determine it any data was recorded for any period of interest, the programsMEPPEN6, MEPPEN7, MEPPEN8, MFPPEN9, MEPPENO, MEPPENI, MEPPEN2, and MFPPEN have

been designed to produce the Raw Data Tape Directories given in Tables ?, 3, 4,

5, 6, 7, 8, and 9. They are formatted on a calender year basis with the

month-of-year along the abscissa and the day-of-month along the ordinate. The

day-of-month is divided into two twelve hour periods as A.M. ( 00:00 to 11:59

hours ) and P.M. ( 12:00 to 23:59 Hours ). The values in the columns headed AM

and PM are the labels of the data tapes that contain the data for those half-day

periods. The value 0 represents either the case that no data was recorded for

that twelve hour period or that the month does not contain 31 days.

A careful review of these figures reveals that a given tape may contain a

large number of data half-days, while others are in use only for a few

half-days. This discrepancy is due to the fact that the data logger samples

the data channrels with dfferent sampl ing rates. If a large number nf one

second or four sccond data channels are sampled and recorded, the data tape

last., For two or three days. If the station operator disables some oi these

1. Digital ceilometer is recorded on the discrete digits of channel 0 as:Discrete "tens" = hundreds of ceiling meters.Discrete "units" = tens of ceiling meters.Installed October, 1980. Operational since March, 1981.

2. Digital rain gauge is recorded on the discrete digits of channels 16and 17 as : Discrete "units" of channel 17 = 100's rain count.

Discrete "tens" of channel 16 = 10's rain count.Discrete "units" of channel 16 = units rain count.These "counts" are multiplied by 25.0

3. Digital sun sensor is recorded on the "tens" digit of channel 37 as:If discrete "tens" digit = 2 or 3, the sun is shining.If discrete "tens" digit = 0 or 1, no sun (cloudy or dark).

Operational since June, 1979.

4. As various instruments were removed from service, the Station Operatorswere able to delete the sampling of the data channels assigned to thoseinstruments, which is reflected in the extended recording timeintervals of the raw data tapes.

5. Data channel numbers designated by the character indicate sensorassignments at the field site.

lowers and [)irhr an (lOO) processes the laser datd at all scanr cl ,s, r,,h( r

thar ot fixed anole. Due to the extended time periods of potnt ieIly use0ul

data, F, fixed agle plot is morp useful in determing these periods wher a

(1 niled aralysis would be required. The prncram IASTPLI was develoPc(' Ifr

'his purpose and is dt- cribed bplow.

The procedure FASTPLT is contained in the permanent file:

L ASERPROCFILEXC3664

FASTPLT will generate compressed time plots (approximately one paqe rrr

four-day period) for a portion or the whole of the ctripped minute chanr-l file

(about one month). The benin time ard end time are parameters, as well as t, e

laser scatterinq angle. All points plotted by this procedure are associated

with this selected scattering angle. All points outside a four degree window

(entered at this angle will be ignored. On the plot, Figure 3, the PAR (C.

, the AEG (CH.O), and the ELTRO (CH.4) are displayed. Table 13 prpsentc--

The interval monitor program for the tower instruments was developed to

assist in both determining individual sensor responses and to contrast the

responses of the six AEG extinction meters, the two ELTRO transmissometers, the

two Barrps transmissometers, and the Ceiling Meter. This package was developed

as a usr-called procedure file as described below.

The procedure IMONITR (Interval Monitor) is contained in the permanent file:

files. These changes are reflected in Table 17. Format of the Revised Hourly

OPAQUE Data Bank File. The hourly OPAQUE Data Bank Files are identified a,, the

"ERIKfiles" .

Considerable reprocessing of the ERIKfiles was preformed to correct for the

the differences in the ELTRO calibration software differences between these

files and the LVD files, and to add data words 64 and 65 (the Barnes 15CO m.

measurements) to the ERIKfiles from March, 1978 onward. These "corrections"

were hdndled as 'replacements' to the hourly files which had been originally

produced by the University of Lowell team and subsequently further processed at

AFGL.

Concurrent with the reprocessing of the ERIKfiles as discussed above, the

Low Visibility Data files were reprocessed t3 take advantage of the availability

nf the data base minute files. Changes to the LVD files were limited to the

replacement of the ELTRO calibration default offset of 30 by a zero offset

value, and a correction to a Barnes filter position software error beainning

with the LVD data tapes for January, 1978.

11.5 LOW VISIBILITY DATA TAPE DIRECTORY.

The low Visibility data files that are produced by the software package

described above are recorded on magnetic tapes issued, cataloqued, and stored at

the A.F.G.L. Computer Center. Table 16. the Computer Center (CC) Low VisiHility

Data Tape Directory, lists all of the active CC tapes by tape number and the

data intervals represented.

NOTE: 1978* tape files have no threshold, all other tape files are with

threshold.

After gaining some experience with the generation of this data set, it was " -

determined that the short runtime of the software procedure files, both with and

without the selection 'window', allows a rapid regeneration of either datia set

and eliminates the backup tape requirement.

11.6 ERIKFILES DATA FILE PRODUCTION AND MODIFICATIONS

OPAQUE siie was changed significantly in the Fall, 1980. The reconfiguratior of

the instruments and the additional measurements added to the data set required

redefinition of the contents of the data words in the post-OPAP1UF data bark

Raw data tape #229 was not successfully stripped.

Production of Nephelometer Data files

An organized production scheme was developed to facilitate generation of

nephelometer data files by data-terminal operators. This was done to simplify

what would otherwise be a somewhat complicated production process (a number of

raw data tapes must be stripped to generate a single month's file). Figure 5

shows a form used hy the terminal-operator during the generation of a single

mtonth's file (JAN79 shown).

11.4 LOW VISIBILITY DATA FILE PRODUCTION AND MODIFICATIONS.

* The production of the Low Visibility data files has been carried out in two

formats, with anid without the minimum visibility 'window'. These files have

been used for both data analysis and to test the consistency of the data values

reported.

Around January, 1983 reprocessing of both LVD and FRIK-files was initiated

to co~rrect for differences in the treatment of calibration data of the

1- Utro-trancvni ssometer. The ERIK-file program looked ahead t~o obtain a

(dilibrdtion count on the half-hour, and then incorporated the calibration count

only ifit was less than 100. Otherwise the last previously accepted calibration

,ourd was used. On startup, a default calibration count of 7ero was assumed.

For consistency, the later Eltro-calibration software Oeveloped for the

LVD-files was incorporated into the ERIK-file program, with the following

a djiustment: The startup Eltro dofault-cal, otion count was set equal to zero

for both the ERIK anid the LVD-file generation.

Eight of the nine raw data tapes were successfully stripped to yield data

used for this purpose.

CONCLUSIONS.

The raw data base, representing over seven years of continuous measurements,

has been edited, stripped, reformatted and re-recorded for analysis and study.

The use of back-up tape copies has been the rule in dealing with the stripped

data tapes. In later production runs for specific measurements, the use of a

back-up tape copy was determined by the procedures and their run-times on the

computer system.

The final packages of programs and control procedures allow one to search

the data base for measurement parameters in a rapid manner through the use of a

procedure file that links all the required programs and data sources in a

time-ordered sequence. By studying the format of the procedure files provided,

one can design a new procedure file for displaying various sensors together in

the same plot or graph.

All of the raw data tapes ;.ave been catalogued and stored for possible

future use in the analysis of the measurements that used a sampling rate greater

than once a minute.
