CEOS Instrument: Aquarius L-Band Scatterometer

Instrument:Aquarius L-Band Scatterometer
Agencies: NASA [Primary]
Mission: SAC-D/Aquarius
Type:Radar scatterometer
Description:L-band scatterometer to provide roughness corection to brightness temperature
Spatial Resolution: 100 km
Swath Width: 300 km
Wavebands: L-Band (1.2 GHz)
Technology: Radar scatterometer
Description: Radar with very accurate calibration, to observe an earth’s spot from several directions (ahead, after, aside) and measure differential backscatter coefficients (s0) from sea capillary waves (thus observing surface wind). On land, the s0 are correlated with soil moisture. Two concepts exist: electronic scanning, side looking, exploiting C-band (~ 5 GHz); and conical scanning, exploiting Ku-band (~ 13 GHz). The resolution is typically 25-50 km, the swath 1100-1500 km. Applicable only in LEO.
