L2 AMSR-E data products are now available through the GHRC DAAC.

The following message has been distributed by the AMSR-E SIPS and announces the availability of near-real-time AMSR-E data products through the GHRC DAAC. The LANCE-MODIS system will continue to generate AMSR-E products through Friday, October 15, 2010. If users detect any significant differences between the data products available from the two locations, please inform Karen Horrocks at and Sherry Harrison at

The Advanced Microwave Scanning Radiometer - Earth Observing System Science Investigator-led Processing System (AMSR-E SIPS) at the Global Hydrology Resource Center (GHRC DAAC) would like to announce the availability of AMSR-E near-real-time data products. The AMSR-E SIPS at the GHRC DAAC has generated climate research quality data products, since the launch of Aqua in the spring of 2002. Now, with the implementation of the Land Atmosphere Near-Real-Time Capability for EOS at the processing facility in Huntsville, the LANCE AMSR-E near-real-time products, with noted limitations, are generated and available to registered users via standard FTP with an average latency of less than 3 hours. The following near real-time data products are available:

  • NRT AMSR-E/Aqua L2A Global Swath Spatially-Resampled Brightness Temperatures (Tb)
  • NRT AMSR-E/Aqua L2B Global Swath Ocean Products derived from Wentz Algorithm
  • NRT AMSR-E/Aqua L2B Surface Soil Moisture, Ancillary Parms, & QC EASE-Grids
  • NRT AMSR-E/Aqua L2B Global Swath Rain Rate/Type GSFC Profiling Algorithm
  • NRT AMSR-E/Aqua Daily L3 Global Ascending/Descending .25x.25 deg Ocean Grids
  • NRT AMSR-E/Aqua Daily L3 Global Snow Water Equivalent EASE-Grids
  • NRT AMSR-E/Aqua Daily L3 6.25 km 89 GHz Brightness Temperature (Tb) Polar Grids
  • NRT AMSR-E/Aqua Daily L3 12.5 km Tb, Sea Ice Conc., & Snow Depth Polar Grids
  • NRT AMSR-E/Aqua Daily L3 25 km Tb and Sea Ice Concentration Polar Grids
  • NRT AMSR-E/Aqua Daily L3 Surface Soil Moisture, Interpretive Parms, & QC EASE-Grids

While not a substitute for climate research quality products, near-real-time products are in high demand in fields such as numerical weather prediction and forecasting, monitoring of natural hazards, disaster relief, agriculture and homeland security. More information about LANCE AMSR-E near real-time data is available at

Standard science products should be used for latency independent research and applications, long term studies and trend analyses. These datasets are available from the National Snow and Ice Data Center (NSIDC) Distributed Active Archive Center.
