Earth Observation System Data and Information System Metrics Report

EOSDIS FY2012 Annual Metrics Report Prepared By: Hyo Duck Chang Adnet, Inc. Brian Krupp Adnet, Inc. Lalit Wanchoo Adnet, Inc. February 2013

Preface 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. During FY2012, additional metrics were collected in the EMS. OBPG has provided its distribution metrics to the EMS since May 2012 and the OBPG metrics used in this report are obtained from the EMS for June - September 2012 and the OBPG website for October 2011 - May 2012. Two other new sources are LPDAAC DEM and LPDAAC LTA providing the ASTER GDEM metrics. Format changes made to FY2012 are: 1) addition of a Land Atmosphere Near Real-time Capability for EOS (LANCE) summary table and 2) inclusion of the CALIPSO metrics in ASDC. Previously the CALIPSO metrics were presented in a separate spreadsheet. 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 jeanne.behnke@nasa.gov or Kevin Murphy at (301) 614-5580 or kevin.j.murphy@nasa.gov. February 2013 FY2012 Annual Report 2

Introduction This report presents statistics on data metrics and web activities at the EOSDIS DAACs during Fiscal Year 2012 (October 1, 2011 through September 30, 2012) 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 FY2012 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 spreadsheet and their metrics are not used in the distribution trend analyses presented in this report. A separate summary table, called LANCE Summary, for NRT products is added to the FY2012 Report. Beginning in FY2012, the CALIPSO metrics are included in the ASDC tables and their metrics were used in the trend analyses. All bots-related distributions (downloads by Internet search engines for indexing purposes) are excluded in the ASF metrics. Definitions for terms used in this report can be found in the Definitions worksheet. February 2013 FY2012 Annual Report 3

LANCE Web Metrics LANCE 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. # Unique Visitors 30,412 27,792 22,390 30,370 39,127 34,690 31,455 25,294 26,583 31,973 32,581 24,017 Month # Visits # Views Oct-11 Nov-11 Dec-11 Jan-12 Feb-12 Mar-12 Apr-12 May-12 Jun-12 Jul-12 Aug-12 Sep-12 47,159 43,428 35,531 47,783 61,780 57,351 53,487 44,372 47,452 58,188 55,807 40,133 512,159 490,060 417,321 570,141 714,987 645,190 617,357 500,589 520,033 637,084 548,885 408,721 FY2012 592,471 6,582,527 325,462 February 2013 February 2013 FY2012 Annual Report FY2012 Annual Report 27 27

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).

Definitions (1 of 3) 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 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. Metrics 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) 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 DAAC 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 science data or metadata 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. In counting unique products, A product having two different version numbers was considered two unique data 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 GBs) successfully delivered to Public users. This includes all file types, including METADATA. February 2013 FY2012 Annual Report 36
