  1. Science Review Panel Meeting Biosphere 2, Tucson, AZ - January 4-5, 2011 Vegetation Phenology and Vegetation Index Products from Multiple Long Term Satellite Data Records ESDRs Distribution and User Support – Miscellaneous Topics Calli Jenkerson ERT, USGS EROS Center NASA MEASURES #NNX08AT05A

  2. MEaSUREs VIP Miscellaneous Topics January 2011 Calli Jenkerson, ERTUSGS EROS Center

  3. Miscellaneous Topics • Beta ESDR File Transfer • Metrics • GMCD Entry • ESDR Metadata • Long Term Archive • ESDR Access -3- MEASURES VIP ESDRs Science Review Panel

  4. Beta ESDR File Transfer • Expectations • Test data set characteristics • Infrastructure • Schedule • Current test results • Plans • Questions -4- MEASURES VIP ESDRs Science Review Panel

  5. Beta ESDR File Transfer • ESDR production at University of Arizona • Storage and distribution at USGS EROS • Expected final totals: • Number of Files <=87,656 • Uncompressed Volume ~5.7 TB • Compressed Volume ~1.5 TB • based on 30 year record • 2 daily products (VI, Phenology) • 4 data sets (AVHRR2, AVHRR3, MODIS, SPOT) -5- MEASURES VIP ESDRs Science Review Panel

  6. Beta ESDR File Transfer • Beta collections available as of June 2010 -6- MEASURES VIP ESDRs Science Review Panel

  7. Beta ESDR File Transfer • Utilize FTP • UofA pushes to public staging area at EROS • ~2 TB disk • Unique VIP user • EROS moves files across firewall to VIP storage • ~6 TB disk -7- MEASURES VIP ESDRs Science Review Panel

  8. Beta ESDR File Transfer • Schedule • Roughly once every year • July 20 - August 3, 2009 • June 7-11, 2010 • June 2011 • December 2011? • June 2012? • As data are available -8- MEASURES VIP ESDRs Science Review Panel

  9. Beta ESDR File Transfer • Test results • 2009 Transfer Test • Alpha data collection • Pushed 230 GB • Obstructed by limited connections (5) to staging area • <1 Mbs average throughput -9- MEASURES VIP ESDRs Science Review Panel

  10. Beta ESDR File Transfer • 2010 Transfer Test • Beta data collection • Pushed 309 GB • Initiated multiple sessions to maximize number of connections to staging area • ~1.7 Mbs continuous throughput -10- MEASURES VIP ESDRs Science Review Panel

  11. Beta ESDR File Transfer • Perform transfers to the EROS VIP environment as ESDR data are available • Not likely to explore performance enhancement • Timeliness of public product availability is not currently an issue for this historical collection • Future plans to archive ESDRs in LP DAAC will not use the beta transfer model for ingest -11- MEASURES VIP ESDRs Science Review Panel

  12. Beta ESDR File Transfer • Questions? -12- MEASURES VIP ESDRs Science Review Panel

  13. Metrics • Expectations • Tools • Record of Report • ESDSWG-MPARWG • Plans • Questions -13- MEASURES VIP ESDRs Science Review Panel

  14. Metrics • Report project metrics as appropriate to mark progress and results • Ingest metrics: volume and number of files stored in EROS VIP systems • Distribution metrics: Web site hits, distinct users, services invoked, file downloads • User metrics: registered users, user services contacts, method of contact, subject of inquiry, escalation level, response time -14- MEASURES VIP ESDRs Science Review Panel

  15. Metrics • Earth Science Data Systems (ESDS) Metrics Collection Tool (MCT) • Established for REASoN projects • Carried over for MEaSUREs • Earth Science Data and Information System (EOSDIS) Metrics System (EMS) • Established for Earth Observing System (EOS) data centers • Potential for implementation of EMS-MEaSUREs -15- MEASURES VIP ESDRs Science Review Panel

  16. Metrics • VIP Metrics Reporting Record: • ESDS MCT entry • 2009 July • 2010 July, September, November • Ingest and Distribution metrics only • Describes primarily test community activity • User metrics will be added as Project-specific after public release of ESDRs -16- MEASURES VIP ESDRs Science Review Panel

  17. Metrics -17- MEASURES VIP ESDRs Science Review Panel

  18. Metrics -18- MEASURES VIP ESDRs Science Review Panel

  19. Metrics • Solicitation requirement to participate in the Earth Science Data System Working Groups (ESDSWG) • VIP has interested parties in Standards and Interfaces, Technology Infusion, Architecture and Reuse Working Groups • VIP is a contributing member of the Metrics Planning and Reporting Working Group (MPARWG) -19- MEASURES VIP ESDRs Science Review Panel

  20. Metrics • Attended ESDSWG Meetings 2009, 2010 • Participated in ESDSWG MPARWG Telecons 2009, 2010 • Contributions: • Experiences • Goals • Feedback • Recommendations -20- MEASURES VIP ESDRs Science Review Panel

  21. Metrics • Continue membership in MPARWG • Respond as needed to MPARWG chairs • Continue quarterly reporting in ESDS MCT • Refine metrics collection methods to more precisely express services rendered -21- MEASURES VIP ESDRs Science Review Panel

  22. Metrics • Questions? -22- MEASURES VIP ESDRs Science Review Panel

  23. GCMD Entry • Global Change Master Directory • NASA sponsored repository for Earth and environmental science information • Data sets • Data services • Intended to consolidate such things into a one-stop-find-everything-site -23- MEASURES VIP ESDRs Science Review Panel

  24. GCMD Entry • Platform • Instrument • Originating Center • Data Center • Distribution • Contact • Pubs/Refs • Uses keywords to navigate through a topical database • Every NASA product is described by • Entry ID • Summary • Geographic Coverage • Data Set Citation • Temporal Coverage • Location / Science Keywords • ISO Topic Category -24- MEASURES VIP ESDRs Science Review Panel

  25. GCMD Entry • Adding a data set is a simple matter of completing a web form • Approval for addition is at GCMD discretion • Preference given to data sets with: • Compliant metadata (ECS or ISO) • Relevance to at least one of about 1,500 science topics -25- MEASURES VIP ESDRs Science Review Panel

  26. GCMD Entry Sample GCMD Entry -26- MEASURES VIP ESDRs Science Review Panel
