1. AMSR2 NRT Land, Atmosphere Near real-time Capability for EOS (LANCE) Helen Conover Information Technology & Systems Center The University of Alabama in Huntsville hconover@itsc.uah.edu

2. Land, Atmosphere Near real-time Capability for EOS (LANCE) Is part of NASA’s Earth Observing System Data and Information System (EOSDIS) https://earthdata.nasa.gov/data/near-real-time-data/about-lance Initiated and sponsored by NASA in 2009 to ensure the availability of NASA satellite data products to those partners who have grown to rely on those data for their decision support systems Provides Near-Real-Time (NRT) EOS data products within 3 hours of satellite observation with high availability LANCE Data contributed to the successful forecast of hurricane Sandy User Working Group Meeting

LANCE AMSR2 System Overview LANCE AMSR2 Level 2 and Level 3 processing at AMSR SIPS (GHRC) Worldview https://gcom-w1.jaxa.jp AMSR2 NRT L2, L3 daily Science data JPG/PNG imagery GIBS gwen.nsstc.nasa.gov lance.nsstc.nasa.gov EOSDIS User Registration System (URS) Data Ingest & Processing LANCE Web & FTP Server JAXA GCOM-W1Data Providing Service APID packets L1R lance.itsc.uah.edu gwen.itsc.uah.edu Registered Users metadata ECHO LANCE Web & FTP Server Data Ingest & Processing LANCE AMSR2 NRT data product in HDF-EOS5 KSAT Svalbard Ground Station • Redundant processing strings on 2 independent networks in different buildings will greatly reduce the possibility of data being unavailable due to system outages • LANCE AMSR2 NRT data products will be available at AMSR SIPS on GHRC DAAC, for 7-14 days

5. Approach AMSR Science Team Meeting • Leverage as fully as possible the LANCE AMSR-E hardware and software architecture • Ingest from JAXA, rather than NASA GSFC EDOS • Preliminary AMSR2 science algorithms provided by the US AMSR2 Science Team • Processing automation software will be very similar, but require changes to accommodate new file names, etc. • Documentation, including metadata and quality assessment, will require updates to accommodate differences in instrumentation • Implement new requirements per 423-RQMT-002 • Integrate with the ESDIS URS4, including HTTPS access • Register data granules within EOS Clearing House and Common Metadata Repository

6. AMSR2 NRT Products • Integrated the GPROF2010 (GSFC Profiling) retrieval code for a near real time AMSR2 precipitation and non-raining parameters product into the SIPS production environment. • The algorithm has been compiled with GFortran on a 64-bit LINUX system and produces the same results as the CSU-provided binary sample files • Next efforts are to define requirements and implement metadata and GIBS browse.

7. AMSR2 NRT Products (2) Preliminary AMSR2 SWE Algorithm (AMSR-E SWE) JAXA Level-1R (HDF5) Level-3 Snow Product (HDF-EOS5) AMSR Science Team Meeting Integrated the preliminary AMSR2 snow water equivalent (SWE) algorithm into the SIPS production processing system. The algorithm has been compiled with GFortran on a 64-bit LINUX system and produces the same results as the CCNY-provided binary sample files Next efforts are to define requirements and implement metadata and GIBS browse.
