EOSDIS FY2013 Annual Metrics Report Summary

EOSDIS FY2013 Annual Metrics Report Prepared By: Hyo Duck Chang, Adnet, Inc. Brian Krupp, Adnet, Inc. Lalit Wanchoo, Adnet, Inc. Young-In Won, Wyle, Inc February 2014

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. 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. 2 February 2014 FY2013 Annual Report

Introduction This report presents statistics on data metrics and web activities at the EOSDIS DAACs during Fiscal Year 2013 (October 1, 2012 through September 30, 2013) 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 FY2013 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 and a separate summary table for NRT products, called LANCE_Summary, is included. Note that NRT metrics are not 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. A new worksheet called "Total Archive Trend" showing various input sources used to derive total archive volumes for previous years is added to this year's report. Definitions for terms used in this report can be found in the Definitions worksheet. 3 February 2014 FY2013 Annual Report

Web Visitors and Visits EOSDIS 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. # Unique Visitors 108,240 102,868 99,780 121,537 108,342 124,486 125,891 111,115 96,441 99,540 94,807 103,626 Month # Visits # Views Oct-12 Nov-12 Dec-12 Jan-13 Feb-13 Mar-13 Apr-13 May-13 Jun-13 Jul-13 Aug-13 Sep-13 155,269 146,333 142,301 175,643 157,054 186,929 188,548 169,621 151,519 163,187 147,278 146,116 2,180,927 2,067,847 1,789,784 2,286,986 2,241,338 2,492,811 2,395,851 2,476,173 1,841,919 2,074,423 1,845,963 1,626,277 FY2013 1,929,798 25,320,299 1,183,040 23 February 2014 FY2013 Annual Report

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. 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. # Unique Visitors 21,350 19,063 26,660 37,224 27,572 34,553 37,541 30,278 25,547 24,125 25,392 19,333 Month # Visits # Views Oct-12 Nov-12 Dec-12 Jan-13 Feb-13 Mar-13 Apr-13 May-13 Jun-13 Jul-13 Aug-13 Sep-13 34,329 30,371 41,774 57,880 45,363 59,186 65,012 52,552 45,918 47,002 43,956 31,963 410,466 421,869 458,322 613,512 482,698 553,389 616,053 534,322 471,203 457,237 423,218 349,630 FY2013 555,306 5,791,919 298,036 27 February 2014 FY2013 Annual Report

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).

Total Archive Trend The 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.

Web Trends Web metrics data for EOSDIS became available as of FY2007. Data for FY2007 is complete for 7 DAACs and FY2008 is complete for 8 DAACs. Since FY2009, 11 DAACs provided web metrics. These metrics are for visits of one minute or more. Repeat visitors are counted as 2 or more visits since web activity measurements began for that DAAC.

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). Data Provider 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 Metrics Web Metrics Domain EMS Data File Term Ingest Definition Ingest is the amount of data coming into a DAAC over a period of time and includes all product levels. 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. The volume of data (in GBs) successfully delivered to Public users. This includes all file types, including METADATA.

Definitions (2 of 3) EMS Data File Term Definition Any 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. Public User 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. Any 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. QA/Test User Production User Internal 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 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. Science Team 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. 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.

Definitions (3 of 3) Report Term Stage 1 Definition Metrics data directly from the EMS tools, presented by data provider as available. Metrics data grouped by DAAC , augmented with external data, includes all twelve DAACs. Grouping is done for the 3 DAACs that have multiple data providers: ASDC DAAC (LARC ANGE, LARC ECS, LARC ORDERS), LP DAAC (LP DAAC, LPDAAC DEM, LPDAAC MRTWEB LPDAAC LTA) and NSIDC DAAC (NSIDC, NSIDC SRCHLT, NSIDC V0). Metrics data presented by the major contributing DAACs, often accompanied by a graphic. Stage 2 Stage 3 39 February 2014 FY2013 Annual Report
