Preface

2January 2015 FY2014 Annual Report

The Earth Sciences Data and Information System (ESDIS) Project (Code 423) prepared the following report on metrics from across the Earth Observation System Data and Information System (EOSDIS). The 12 Distributed Active Archive Centers (DAACs) of EOSDIS support different scientific disciplines and provide an individualized set of products and services to their science community and the public. Although discipline oriented, the DAACs engage in common data management functions of ingest, archive and distribution, as well as describing their data and services on web sites.

Metrics are collected on a daily basis from each DAAC. The ESDIS Project collects these metrics in a tool called the ESDIS Metrics System (EMS). DAAC analysts can view their detailed metrics to assess internal performance and trends. The ESDIS Project combines these metrics, not for comparisons between the DAACs, but as a system level view of EOSDIS performance. This report provides snapshots of metrics as the combination of the individual DAACs and as a system.

In keeping with previous years, and in order to support trend comparisons, the metrics data are presented on a fiscal year basis, not by calendar year. These reports are posted online with metrics as far back as 1996. Each report includes some historical trend information.

If you have any questions or comments, please contact Jeanne Behnke at (301) 614-5326 or [email protected].

Introduction

January 2015 FY2014 Annual Report3

This report presents statistics on data metrics and web activities at the EOSDIS DAACs during Fiscal Year 2014 (October 1, 2013 through September 30, 2014) from the Earth Science Data and Information System (ESDIS) Metrics System (EMS).

EMS supports the ESDIS project management by collecting and organizing various metrics from the Earth Observing System (EOS) Data and Information System (DIS) DAACs and other sources. The EMS collects and presents data on the usage of products and services delivered via the Internet or managed in EOSDIS archives.

EMS consists of a Data Metrics component and a Web Metrics component. The Data Metrics component provides statistics on data ingest, archive and distribution plus data users profile information. The Web Metrics component provides statistics on web site visits, views and visitors with a variety of related parameters.

This report contains tables and graphs of FY2014 statistics and comparisons to previous years. Values for previous fiscal years are produced from EMS unless noted otherwise. Summary tables, text, graphs, and more detailed statistics tables are also included. As before, metrics for the Near Real-Time (NRT) products are presented in a separate worksheet including unregistered users distribution and a separate summary table for NRT products, called LANCE_Summary, is included. Note that NRT metrics are used in the distribution trend analyses presented in this report. All bots-related distributions (downloads by Internet search engines for indexing purposes) are excluded in the ASF metrics. Also, this year's report includes the data from S-NPP CERES instrument archived and distributed by ASDC and data distribution from AQUARIUS and ISS missions by OBPG. Three new worksheets have been added to this year's report and they are: 1. "Earthdata Webmetrics" showing netinsight webmetrics for the Earthdata website for FY2014, 2 "Product Level Trend" showing data distribution by product level for FY 2014, and previous years and 3. "Data Availability" showing the daily data availability in the EMS. In addition have added Earthdata web trend for FY2012 to FY2014 in the "Web Trends" tab.

Definitions for terms used in this report can be found in the Definitions worksheet.

* Excludes metadata** Represents the number of unique IP hosts/e-mail addresses used to retrieve NRT products, excluding registered users*** Represents the number of the registered users who retrieved data for each instrument. It must be noted that sum of theses users may be greater than the total number of unique registered users since one user could retrieve data for multiple instruments1 These products do not have any mission or instrument mapping but have been distributed, such as ancillary data.

Near Real-time (NRT) Distribution provides the amount of data successfully distributed to registered users of the Land Atmosphere Near Real-time Capability for EOS (LANCE). LANCE provides access to near real-time data (<3 hours from observation) from MODIS, AIRS, MLS and OMI instruments. Metrics for distribution volume, numbers of files distributed and users are presented.

Web Visitors and VisitsEOSDIS web activity is measured by number of Visits made, the number of pages Viewed and the number of distinct Visitors. Visits of at least one minute are considered to represent significant work accomplished, and many of the shorter visits are of less than a second. Eleven of the twelve EOSDIS DAACs report web metrics at this time; all except OBPG. Note that the sum of monthly visitors could be greater than the number of unique visitor for a given year since one user could be counted more than once if he/she visited the same website in different months. Excludes Earthdata website activity.

Visits of at least one minute are considered to represent significant work accomplished, and many of the shorter visits are of less than a second. This is for Earthdata website only. Note that the sum of monthly visitors could be greater than the number of unique visitor for a given year since one user could be counted more than once if he/she visited the same website in different months.

LANCE Web MetricsLANCE web activity is measured by number of visits made, the number of pages viewed and the number of distinct visitors for the LANCE website. The number of hosts counts the distinct IP addresses of the visitors. Repeat visitors is a count of those visitors who made at least two visits since the start of web activity measurements or in the fiscal year.

Web metrics are presented for visits of one minute or greater. Visits of at least one minute are considered to represent significant work accomplished, and many of the shorter visits are of less than a second. The sum of monthly visitors could be greater than the number of unique visitors for a given year since one user could be counted more than once in the monthly visitor count if he/she visited the LANCE websites in different months.

Total UsersTotal Users is an estimate formed by combining the distinct Data Users and distinct Web Visitors, removing the overlap and excludes LANCE Unregistered users who downloaded browse imagery. The common element for these counts is the IP address (Host); therefore, the comparison is made without using the additional details provided by the Data User email address or the Web Visitor browser. Not being able to compare the users directly likely results in an undercount. Web Visitors included in the count are for those visitors with visits of one minute or longer. To minimize the undercount, the final Total Users value includes the total Web Visitors (IP address plus browser), plus the distinct Data Users (counted by IP Address).

Total Archive TrendThe total archive trend is based on data and reports produced during individual fiscal years, rather than from EMS. EMS does not contain sufficient information to recreate the archive size for previous years due to episodic deletions from the archive and not all archive information is supplied to EMS by the DAACs. Since products are deleted at the DAACs and not always reported to EMS, It may not able to completely reproduce what was in the archive in previous years.

The trend data were compiled in FY2013 with the expectation it will be updated yearly with data captured in that year's EOSDIS Annual Report in the Total Archive Size worksheet. The sources of data for earlier years , which are not presented here, are available from the Excel version of this report.

EMS Term Definition

Data ProviderEOSDIS element serving as a source of metrics information for describing the ingest, archive and distribution of EOSDIS science data; web activity metrics are also collected. For the EOSDIS annual reporting, metrics from individual data providers at a single site are combined (e.g., NSIDC = NSIDCECS + NSIDCV0).

Data Metrics

Metrics describing the ingest, archive and distribution of EOSDIS science data at EOSDIS DAACs. This EOSDIS Annual Report presents data metrics from EOSDIS DAACs. Most metrics can be found in the EMS HTMLDB interface (http://ops1.ems.eosdis.nasa.gov: 8000/pls/apex/f?p=111). Metrics from other sources are noted in the report where applicable.

Web MetricsMetrics describing the web activity at EOSDIS DAAC web sites and EOSDIS related web sites. This EOSDIS Annual Report presents web metrics by EOSDIS DAACs. These metrics can be found in the EMS NetInsight interface (https://ops-ni.ems.eosdis.nasa.gov/NetInsight/index.html)

DomainDesignates the type of business or organization accessing EOSDIS. The domain is determined from the IP address and country.

EMS Data File Term

Definition

Ingest Ingest is the amount of data coming into a DAAC over a period of time and includes all product levels.

Archive Archive is the amount of data added to the archive over a period of time and includes all products levels.

Total Archive SizeThe Total Archive Size describes the EOSDIS archive at the end of the fiscal year. This includes all data (including ancillary) but not data marked for deletion.

Data User Any individual requesting data as defined by an IP address plus email, within the time period.

Distinct Users The number of distinct (i.e., counted once) users receiving science data or metadata during the report period.

GranuleThe smallest unit of data inventoried and distributed to users; typically, a granule is a single data file, though some granules may include multiple files.

Product

EMS counts individual files as distinct products. This is roughly equivalent to counting EOS granules, although in the case of some EOS instrument data, a granule may contain more than one file. If so, the files are counted as individual products. In counting unique products, A product having two different version numbers was considered two unique data products.

Number of Products Delivered

The number of files successfully delivered to Public users. This count excludes METADATA file types. If the file type does not distinguish a file as a metadata or a science file, i.e., it is encoded as n/a, then the default process is to count the file as a science data product.

Volume of Products Delivered

The volume of data (in GBs) successfully delivered to Public users. This includes all file types, including METADATA.

EMS Data File Term

Definition

Public UserAny user who uses products obtained from the Data Providers for scientific or other uses. If a data provider does not assign user categories EMS automatically assigns all distributions to this category.

QA/Test User Any identified and authorized user who requests data for the purposes of quality assurance/testing.Production User Any identified and authorized user who requests data for the purposes of product generation.

Internal UserAny user (human or machine) that transfers data inside the data providers network space for the purpose of backups, internal testing, hardware migration, temporary staging of standard products, etc.

Science Team User

Any user formally associated with a defined EOS Science Team using data for objectives of the respective Science Team. If a Science Team user acts in dual capacities (e.g. as a Science Team User and a Public User) the user must use different credentials to access data or user will be assigned to science user by EMS.

All Users All distinct Public users requesting data within the time period.

Repeat UsersDistinct Public users requesting data more than once during the time period. If the user is requesting data for the first time ever within the specific time period and then requests data again during the specific time period, he/she would be counted as a repeat user.

EMS Web File Term

Definition

VisitorAny individual defined by IP Address+browser that views a web page. A visitor can also become a 'Data User' once data is requested.

Distinct Visitors The number of distinct (i.e., counted once) visitors to a provider's web sites during the time period.

ViewHit by a user during a session to a web page, excluding error hits and hits to user-defined files such as inline images (.JPG, .GIF, etc.), Java applets, and specific redirects or services provided by the data provider.

VisitA series of consecutive views of a website by the same user without continuous interruption of more than 30 minutes. If a user does not view a new page in a specified time, the next page viewed by that user is considered the start of a new visit.

EMS Web Views The number of page views to a provider's web pages over the time period. EMS Web Visits The number of visits over the time period.All Visitors All distinct visitors viewing a web page during the report time period.

Repeat Visitors

Visitors who view a web page during a specific time period who have accessed the system before. If the visitor accesses the system for the first time ever within the time period and then accesses the system again during the specific time period, he/she would be counted as a repeat visitor.For EOSDIS we track Repeat Visitors two ways: 1) since the start of web measurements to provide an historical count; and 2) since the start of the Fiscal Year to count activity specific to this Annual Report.
