1. EOSDIS FY2009 Annual Metrics Report Prepared By: Hyo Duck Chang Adnet, Inc. Brian Krupp Adnet, Inc. Lalit Wanchoo Adnet, Inc. March 2010

2. Preface The Earth Sciences Data and Information System (ESDIS) Project (Code 423) is pleased to present the following report on metrics from across the Earth Observation System Data and Information System (EOSDIS). The 12 Data Centers 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 data centers 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 data center. The ESDIS Project collects these metrics in a tool called the ESDIS Metrics System (EMS). Data center analysts can view their detailed metrics to assess internal performance and trends. The ESDIS project combines these metrics, not for comparisons between the data centers, but as a system level view of EOSDIS performance. This report provides snapshots of metrics as the combination of the individual data centers and from a purely system perspective. The EOSDIS Annual Report for FY2009 (Oct. 1, 2008 Sept. 30, 2009) presents a best effort to combine and present information from the collected metrics data. Some data centers are in the process of developing their interfaces with the EMS and testing is not yet complete. Therefore, some data centers do not yet deliver metrics data in all parameter categories these will be added in future reports. 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. If you have any questions or comments please contact Jeanne Behnke at (301) 614-5326 or jeanne.behnke@nasa.gov or Kevin Murphy at (301) 614-5580 or kevin.j.murphy@nasa.gov. March 2010 FY2009 Annual Report 2

3. Introduction This report presents statistics on data metrics and web activity at the EOSDIS data centers during Fiscal Year 2009 (October 1, 2008 through September 30, 2009) 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) Data Centers and other Data Providers. 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 collected from Data Providers. 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 FY2009 statistics and comparisons to previous years. Values for previous fiscal years are produced from EMS. Summary tables, text, graphs, and more detailed statistics tables are also included. Definitions for terms used in this report can be found at the end of this presentation.

24. Total Users Total Users is an estimate formed by combining the distinct Data Users and distinct Web Visitors, removing the overlap. 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).

31. Definitions (1 of 2) EMS Term Definition EOSDIS 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). Metrics describing the ingest, archive and distribution of EOSDIS science data at EOSDIS Data Centers. This EOSDIS Annual Report presents data metrics from EOSDIS Data Centers. 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. Metrics describing the web activity at EOSDIS Data Center web sites and EOSDIS related web sites. This EOSDIS Annual Report presents web metrics by EOSDIS Data Centers. These metrics can be found in the EMS NetInsight interface (https://ems.eos.nasa.gov/NetInsight/index.html). Designates the type of business or organization accessing EOSDIS. The domain is determined from the IP address and country. Data Provider Data Metrics Web Metrics Domain EMS Data File Term Definition Ingest is the amount of data coming into a data center over a period of time and includes all product levels. Ingest Archive is the amount of data added to the archive over a period of time and includes all products levels. Archive The 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. Any individual requesting data as defined by an IP address plus email, within the time period. The number of distinct (i.e., counted once) users receiving data during the report period. The smallest unit of data inventoried and distributed to users; typically, a granule is a single data file, though some granules may include multiple files. 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. 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. Total Archive Size Data User Distinct Users Granule Product Number of Products Delivered Volume of Products Delivered The volume of data (in MBs) successfully delivered to Public users. This includes all file types, including METADATA. March 2010 FY2009 Annual Report 31

32. Definitions (2 of 2) EMS Data File Term Definition Any individual defined by an IP Address who requests and receives data for purposes other than product generation and quality assurance/testing. Any identified and authorized user who requests data for the purposes of quality assurance/testing. Any identified and authorized user who requests data for the purposes of product generation. All distinct Public users requesting data within the time period. Distinct 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. Public User QA/Test User Production User All Users Repeat Users EMS Web File Term Definition Any individual defined by IP Address+browser that views a web page. A visitor can also become a 'Data User' once data is requested. The number of distinct (i.e., counted once) visitors to a provider's web sites during the time period. Hit 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. A 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. The number of page views to a provider's web pages over the time period. The number of visits over the time period. All distinct visitors viewing a web page during the report time period. 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.
