1. EOSDIS FY2015 Annual Metrics Report Prepared By: Lalit Wanchoo, Adnet, Inc. Young-In Won, Wyle, Inc. Durga Kafle, Adnet, Inc. January 2016

2. Preface 2 January 2016FY2015 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 jeanne.behnke@nasa.gov.

3. Introduction January 2016FY2015 Annual Report 3 This report presents statistics on data metrics and web activities at the EOSDIS DAACs during Fiscal Year 2015 (October 1, 2014 through September 30, 2015) 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 FY2015 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 now included. Also, this year's report includes a data center name change from OBPG to OB.DAAC and the data from all S-NPP instruments archived and distributed by ASDC, MODAPS, and OB.DAAC. Three new worksheets have been added to this year's report and they are: Distribution_Mission_Instrument, Distribution_Mission_Domain, and Distribution_Mission_Level showing the distribution details for Terra, Aqua, and Aura instruments by domain and product levels. One new workbook (FY15Annual_DAAC_Profile) has also been added that provides the summary of archive, distribution, and web metrics for individual DAACs. Definitions for terms used in this report can be found in the Definitions worksheet.

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 instruments 1 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.

26. 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. Excludes Earthdata website activity. 26 January 2016FY2015 Annual Report

27. January 2016FY2015 Annual Report 27 Earthdata 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. 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.

28. Repeat Web Visitors EOSDIS Web Visitors are characterized by the number of visits they make and how frequently they return. Visitors counted in the table below are those that stayed for one minute or more. Repeat Visitors are counted from the start of the Fiscal Year. Metrics data is collected per data center and summed for an EOSDIS total. 28 FY2014 Web Visitors for Visits of one minute or more January 2016FY2015 Annual Report * represents the sum of the metrics from all 11 data centers and excludes Earthdata

33. January 2016FY2015 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. 33 Month# Visits# Views # Unique Visitors Oct-14 25,269278,46316,309 Nov-14 24,684260,97516,526 Dec-14 25,642269,70816,722 Jan-15 34,261341,02622,491 Feb-15 34,883347,84422,431 Mar-15 39,679373,99025,141 Apr-15 37,399359,74322,844 May-15 28,548281,87417,367 Jun-15 24,041234,22713,299 Jul-15 29,532277,33316,071 Aug-15 26,045237,01815,159 Sep-15 19,537181,15212,042 FY2015349,5203,443,353198,199

35. January 2016FY2015 Annual Report 35 Total Users Total 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).

36. 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. 36 January 2016FY2015 Annual Report Volume By FY Total Volume (PBs) FY000.51 FY010.99 FY021.92 FY033.55 FY043.94 FY054.06 FY064.62 FY074.91 FY084.29 FY094.20 FY104.50 FY115.76 FY127.40 FY139.76 FY149.12 FY1514.63
