All LANCE AMSR2 data should be used with the understanding that these are preliminary products. Cross calibration with AMSR-E products has not been performed. As updates are made to the L1R data set, those changes will be reflected in the higher level products. JAXA will have a new version of their AMSR2 Level-1R data (the data used as input to our products) in early 2015.
NASA’s Land Atmosphere Near real-time Capability for Earth Observing Systems (LANCE) leverages existing satellite data processing systems in order to provide data and imagery available from select EOS instruments (currently AIRS, AMSR2, MLS, MODIS and OMI) within 3 hours of satellite overpass. These data meet the timely needs of applications such as numerical weather and climate prediction, forecasting and monitoring natural hazards, agriculture, air quality and disaster relief.
The LANCE element for Advanced Microwave Scanning Radiometer 2 (AMSR2) is co-located with the AMSR Science Investigator-led Processing System (SIPS) at the Global Hydrology Resource Center (GHRC) DAAC in Huntsville, Alabama. The AMSR SIPS is also responsible for the generation of climate research quality products; these products will be available from the National Snow and Ice Data Center (NSIDC) beginning in late 2015.
