Helen ConoverInformation Technology & Systems CenterThe University of Alabama in [email protected]
• 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
Land, Atmosphere Near real-time Capability for EOS (LANCE)
LANCE Data contributed to the successful forecast of hurricane Sandy

Worldview
• 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

Approach• Leverage as fully as possible the LANCE AMSR-E hardware
and software architectureo 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-002o Integrate with the ESDIS URS4, including HTTPS accesso Register data granules within EOS Clearing House and
Common Metadata Repository

AMSR2 NRT Products
9/23/14
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.

AMSR2 NRT Products (2)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.
