GHRC News

The AMSR-E SIPS at the GHRC DAAC would like to announce the availability of AMSR-E near real-time data subscriptions.
With a data subscription, we will push selected data products to a designated computer as soon as the products are generated. In order to receive these products via subscription, you must be a registered LANCE user. Please let us know if you are interested in using our subscription service for AMSR-E near real-time data.

LANCE logoThe AMSR-E SIPS at the GHRC DAAC has implemented incremental daily processing for our AMSR-E near real-time Level 3 daily (Ocean, Land, Snow, Sea Ice ) products. Partial products are created several times per day (currently every 3 hours) using whatever L2 data is available at the time of creation, in order to reduce latency for these products. These partial files are now available in our test areas at

ftp://lance.nsstc.nasa.gov/test/science/
and ftp://lance2.itsc.uah.edu/test/science/.

These partial products (identified by "P") will be available in the same FTP directories as the complete real-time daily products (identified by "R"). Each new partial product for a given day will have the same file name as the previously-generated one, but will incorporate additional input files. A new partial product can be distinguished by creation time shown in the directory listing. Once the full daily file is available the partial file for that day will be deleted.

LANCE logoThe AMSR-E SIPS at the GHRC DAAC would like to announce the expanded availability of AMSR-E near real-time data products through the Land Atmosphere Near-real-time Capability for EOS (LANCE). These near real-time swath and daily products are generally available to registered users within three hours of observation. In order to provide for full system redundancy, the SIPS has implemented a second string ftp server at ftp://lance2.itsc.uah.edu. Users should obtain data from this location in the event that the primary LANCE ftp server (ftp://lance.nsstc.nasa.gov) is unavailable. Both strings are located on the UAHuntsville campus and managed by SIPS personnel, but are located in different buildings and connected to different networks. Redundant processing strings will greatly reduce the possibility of data being unavailable due to system outages.

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 AMSRE-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 (LANCE) 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 http://lance.nsstc.nasa.gov/.

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 (NSIDC DAAC).
