CEOS Instrument: Submillimetre Radiometer

Agency: SNSB
Mission: Odin
Type:Limb-scanning MW spectrometer
Description:Measures global distributions of ozone and species of importance for ozone chemisty, ClO, HNO3, H2O, N2O, (HO2, H2O2). Measures temperature in the height range 15-100km.
Spatial Resolution: Vertical resolution 1.5 - 3 km, along track 600 km
Swath Width: Altitudes of 5 - 100 km
Wavebands: Microwave: 118.7 GHz + 4 bands in the region 480 - 580 GHz: Tunable measures 2 - 3 x 1 GHz regions at a time; ~0.1 cm - ~0.3 cm
Technology: Limb-scanning MW spectrometer
Description: Spectrometer operating in the millimetre-submillimetre range (30-3000 GHz) with spectral resolution typically around 0.01 % required for atmospheric chemistry. Designed to provide high vertical resolution in the upper troposphere and above by scanning the Earth’s limb. Some thousands of channels. Spatial resolution typically 1-3 km vertical, 300-500 km horizontal. Applicable only in LEO.
