AMSR-E LANCE Personnel UAHuntsville ITSC (Staff shared with GHRC DAAC): Management: Dr. Sara Graves, Director, ITSC Development: Helen Conover, Lead Bruce Beaumont Lamar Hawkins Mary Nair Matt Smith Engineering: Kathryn Regner Sandra Harper Data Management: Steve Jones User Services: Sherry Harrison Systems Administration: Will Ellett, Lead Michele Garrett

  4. LANCE AMSR-E Overview • Co-located with the AMSR-E SIPS, TLSCF, and GHRC; well established relationships with the AMSR-E Science Team. The AMSR-E SIPS currently produces the L2 & L3 standard products. • Two fully redundant processing and distribution strings, at separate locations, on separate networks • Seven day rolling archive • Ingest of L0 data directly from EDOS • Products generated within 20 min from acquisition at SIPS, in support of three hour latency requirement

  8. Software Architecture

  9. System Status • Hardware (four servers total for two strings of equipment) has been specified and is in the UAHuntsville procurement process. • Network Interfaces for both strings of equipment have been identified. • A list of firewall exceptions to request from NASA MSFC was submitted on Friday, 4/23. • Firewall exceptions are in place for BBFTP and LDAP. BBFTP is installed on the LANCE AMSR-E interim ingest and processing server, GWEN. 

  10. Network Interfaces

  11. Network Interfaces (2)

  12. Development Status • LANCE MODIS software downloaded and installed on temporary platform (existing AMSR-E SIPS reprocessing server).  • We are now able to generate all AMSR-E LANCE products.  • L1A and L1B, using the same code that JAXA delivered to NSIDC for use by NOAA.   • Level-2A, using RSS code obtained from NSIDC and adapted by NOAA. • Level-2B and Level-3 daily processing, using the same standard product algorithms currently in production at the SIPS.

  13. Development Status (2) • Beginning routine LANCE processing in an extended test mode to evaluate error handling, metrics collection processes, etc. • ingesting and processing IERB data, utcpole.dat, leapsec.dat, orbital events, and other external files via cron as needed • Ready to begin external interface testing to verify connectivity and procedures • Interface testing with EDOS for real-time receipt of RBD and GBAD data and with the ESDIS LDAP server for user registration/authentication.

  14. Development Status (3) • Initial validation has been performed using a few sample L2A files. • L2A files generated at LANCE-MODAPS and LANCE AMSR-E are virtually identical, with very small differences attributed to the differences in compilers and operating systems (64-bit versus 32-bit). • Differences between L2A files generated at LANCE AMSR-E and at the AMSR-E SIPS are more significant, but appear to be due to the fact that different versions of the L2A algorithm are used; LANCE is using V9 and SIPS is using the more current V10. We are working with the AMSR-E TLSCF to evaluate these differences.

  15. Development Status (4) • File naming convention • To distinguish standard products from near real time products, we will use the existing “product maturity code” within the file name, e.g., AMSR_E_L2_Rain_R10_200905281123_A.hdf

  16. Near Term Tasks • End-to-end processing and validation • Implement data distribution to users • Move all processing to production • Prepare DIF entries for the ASMR-E LANCE products to submit to NASA’s Global Change Master Directory (GCMD) • Define and implement metrics process

  17. Schedule • Phase1 (April 1 – June 30): • Implement initial AMSR-E NRT capability equivalent to NOAA & MODAPS on processing hardware borrowed from the SIPS and distribution via the GHRC web ftp server. • Includes preliminary validation, initial user registration/authentication, and metrics • Phase 2 (July 1 – August 30): • Implement initial AMSR-E NRT capability on target hardware at both locations

  18. Schedule (2) • Phase 3 (September 1 – January 30) • Implement latest AMSR-E standard products algorithms • Implement L2A near real time algorithm from RSS. • Provide subscription service, web-based monitoring, ESDIS User registration.

  19. Summary • LANCE AMSR-E processing system is on schedule to become operational in early 2010. • procuring two strings of hardware • leveraging existing SIPS personnel, processes and procedures and software algorithms from the NSIDC DAAC.
