Land Surface Emissivity Data from AMSR-E/Aqua Now Available

Global, monthly land surface emissivity data from the Advanced Microwave Scanning Radiometer – Earth Observing System (AMSR-E) are now available at NSIDC. These data complement existing passive microwave measurements from the Special Sensor Microwave Imager (SSM/I) and Advanced Microwave Sounding Unit (AMSU) by offering land emissivity from 18.7, 23.8, 36.5, and 89.0 GHz, as well from two lower frequencies: 6.9 and 10.65 GHz. According to Principal Investigator, Hamidreza Norouzi, observations from the lower C- and X-band frequencies are able to penetrate deeper into the soil layer.

To access the data and documentation, see the AMSR-E/Aqua Monthly Global Microwave Land Surface Emissivity Web page.
