   Each HDF-EOS file contains core metadata with QA metadata flags that are set 
   by the Science Investigator-led Processing System (SIPS) at the Global 
   Hydrology and Climate Center (GHCC) prior to delivery to NSIDC. A separate 
   metadata file in XML format is also delivered to NSIDC with the HDF-EOS file; 
   it contains the same information as the core metadata. Three levels of quality 
   assessment (QA) are conducted with the AMSR-E Level 2 and 3 products: 
   automatic, operational, and science QA. If a product does not fail QA, it is 
   ready to be used for higher-level processing, browse generation, active 
   science QA, archive, and distribution. If a granule fails QA, SIPS does not 
   send the granule to NSIDC until it is reprocessed. Level-3 products that fail 
   QA are never delivered to NSIDC (Conway 2002).

Group: Summary

   The Advanced Microwave Scanning Radiometer - Earth Observing System (AMSR-E) 
   instrument on the NASA Earth Observing System (EOS) Aqua satellite provides 
   global passive microwave measurements of terrestrial, oceanic, and atmospheric 
   variables for the investigation of water and energy cycles. Soil moisture and 
   other land surface variables are key variables in understanding land surface 
   hydrology and in modeling ecosystems, weather, and climate.

   This gridded Level-3 land surface product (AE_Land3) includes daily 
   measurements of surface soil moisture and vegetation/roughness water content 
   interpretive information, as well as brightness temperatures and quality 
   control variables. Ancillary data include time, geolocation, and quality 
   assessment. Input brightness temperature data, corresponding to a 56 km mean 
   spatial resolution, are resampled to a global cylindrical 25 km Equal-Area 
   Scalable Earth Grid (EASE-Grid) cell spacing. Data are stored in HDF-EOS 
   format, and are available from 19 June 2002 to 3 October 2011 via FTP.
