Group: Summary

   This data set is a global land emissivity product using passive microwave 
   observations from the Advanced Microwave Scanning Radiometer - Earth Observing 
   System (AMSR-E). The data set complements existing land emissivity products 
   from the Special Sensor Microwave Imager (SSM/I) and Advanced Microwave 
   Sounding Unit (AMSU) by adding land emissivity estimates at two lower 
   frequencies, 6.9 and 10.65 GHz (C- and X-band, respectively). Observations at 
   these low frequencies penetrate deeper into the soil layer. Land surface 
   emissivity estimates for this data set were collected at the following 
   vertically and horizontally polarized (V-pol and H-pol) frequencies: 6.9, 
   10.65, 18.7, 23.8, 36.5, and 89.0 GHz. Ancillary data used in the analysis, 
   such as surface skin temperature and cloud mask, were obtained from 
   International Satellite Cloud Climatology Project (ISCCP). Atmospheric 
   properties were obtained from TIROS Operational Vertical Sounder (TOVS) 
   observations to determine the small upwelling and downwelling atmospheric 
   emissions as well as the atmospheric transmission. The data set is in monthly 
   format that is extracted from instantaneous emissivity estimates. Data are 
   stored in HDF4 files and are available via FTP.
