CEOS Instrument: JASON Microwave Radiometer

Agency: NASA
Missions: Jason-1
 OSTM (Jason-2)
Type:Non-scanning MW radiometer
Description:Altimeter data to correct for errors caused by water vapour and cloud-cover. Also measures total water vapour and brightness temperature
Spatial Resolution: 41.6 km at 18.7 GHz, 36.1 km at 23.8 GHz, 22.9 km at 34 GHz
Swath Width: 120 deg cone centred on nadir
Wavebands: Microwave: 18.7 GHz, 23.8 GHz, 34 GHz
Technology: Non-scanning MW radiometer
Description: This MW radiometer has the limited purpose of supporting radar altimeter by providing information on total-column water vapour over the sea. The main channel is centred on the water vapour band at 23 GHz, with one or two windows around. The instrument only points nadir exactly as the radar altimeter, thus provides measurement only along track. The resolution is tuned to that one of the altimeter, typically around 25 km. Applicable only in LEO.
