| AMSR-E/Aqua Monthly Global Microwave Land Surface Emissivity |
|
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.  For more detailed information about the documentation and
