Earth Observing System Data and Information System (EOSDIS) provides access to more than 3,000 types of Earth science data products and specialized services for interdisciplinary studies.  EOSDIS Data Centers are co-located with science facilities, educational institutions, and mission instrument teams.  Each Data Center serves one or more Earth science disciplines.  Each Data Center processes, archives, documents, and distributes data from EOS and heritage instruments. EOSDIS surveys were performed by CFI Group through a contract with the Federal Consulting Group (Dept of Treasury) Survey questions consist of model and demographic questions  American Customer Satisfaction Index (ACSI) model questions remain the same year to year  Minor modifications made to demographic questions NASA provides CFI Group a list of addresses for people who have requested and received data center products  Approximately 25,000 in 2006 (21,000 in 2005)  Separated list of users for each data center  Attention was given to get a balance across data centers CFI sends out invitations and the Survey web site is made available for 3 weeks in the summer Users completed 2953 surveys in 2006 (1,395 in 2005) EOSDIS metrics have been collected, analyzed, distributed for over 10 years. EOSDIS has scored well – on par or better than government benchmarks EOSDIS metrics are analyzed and used for program management and reports.  Reports to NASA HQ for evaluation of EOSDIS performance and effectiveness  Reports to NASA data center mangers, ESDIS Project, and NASA HQ for determining how best to apply resources to support the science community  Annual report since 1993 RDBMS Tables FTP server Web server Import & QC Web server Generate Summaries Operations Log File Data User profiles Product metadata Product search term Page tag manifest Log file manifest UsersAd-hoc Query & Summary Reports SEDAC ORNL NSIDC systems (2) LaRC systems (2) JPL PO.DAAC GSFC systems (3) GHRC EDC LP-DAAC ASF Page Tag Data SEDAC Web ORNL Web NSIDC Web LaRC ASDC Web JPL PO.DAAC Web GSFC Web (3) LP-DAAC Web WIST http https sftp scp Data center configuration information Page Tags Installation script Tracking code NetInsight Page Tag Data Distribution Reports By DAAC Directories GCMD For 2005: 65% said FTP was their preferred method; 22% said download from web Survey  Weekly collection of product transactions from science data centers  Product and user configuration information is updated by data centers  Weekly status reports for monitoring of science instrument data flows  Monthly and annual reports for GSFC management briefings covering the recent trends across systems  Ad-hoc reports for special science data studies - user characterization, access method trends and high-level analysis at the product level for ad- hoc or annual reviews  Real-time collection and posting of user activity at the data center web sites  Page tags are configured and installed by data centers Q12. How did you search for the data products or services you were seeking? (n=2,857) In 2004 ESDIS began conducting annual surveys to determine customer satisfaction. Improving services for MODIS and ASTER will improve overall satisfaction.  Users often selected more than one instrument as the source of data received in their most recent order.  Responses suggest we should conduct further analysis of multi-instrument product searches. Guidance for Science Data Centers through Understanding Metrics Very few users require data delivered on physical media; most users prefer web and ftp for delivery. A significant number of users indicated they would prefer TIFF or GeoTIFF.  Indicates further analysis of survey responses – breakdown by instrument  Suggests metrics collection and analysis could provide better information 2006 Survey Most users access their data through the web.  Anticipate higher utilization of online data systems  Respond to users through analysis of WWW access and product request patterns  Look for Web content and services to enable new and repeat user communities The survey shows that product search continues to be the top opportunity for improving satisfaction.  Responses suggest users prefer data-center specific search tools  Majority of users depend on the EOS Data Gateway – the common cross-data center search tool EOSDIS collects ingest, archive, access, and distribution metrics.  Ingest and archive – what product files were ingested by the data center and when  Corollary: What product files were deleted from the archive  Previous versions of products that have been replaced with a new version after reprocessing  Products that have been moved to other data centers  Distribution - what product files were distributed, by what method, when and to whom  Access – who, when and what they go to at the DAAC  Collection ed weekly from each data center ESDIS metrics collection and analysis reflect changing user access patterns and an increasing use of metrics for project management. Metrics re-engineering will increase insight into user access and take advantage of recent capabilities offered by commercial venders.  New tools for recording and analyzing how users navigate through Web pages, find and access products (NetInsight)  Advanced integration of metrics with Web services RDBMS (HTML DB) WWW access: 2.9 Million users in Million users in 2005
