CEOS Instrument: Microwave Limb Sounder (EOS-Aura)




Instrument:MLS (EOS-Aura)
Agency: NASA
Mission: Aura
Status:Operational
Type:Limb-scanning MW spectrometer
Description:Measures lower stratospheric temperature and concentration of H2O, O3, ClO, HCl, OH, HNO3, N2O and SO2
Spatial Resolution: 3 x 300 km horizontal x 1.2 km vertical
Swath Width: Limb scan 2.5 - 62.5 km Limb to limb
Wavebands: Microwave: 118 GHz, 190 GHz, 240 GHz, 640 GHz and 2.5 THz
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.
