CEOS Instrument: Microwave limb sounder (GACM)




Instrument:Microwave limb sounder (GACM)
Agency: NASA
Mission: GACM
Status:Proposed
Type:Limb-scanning MW spectrometer
Description:Limb-viewing measurements of O3, N2O, temperature, water vapor, CO, HNO3, ClO, and volcanic SO2 in the
Spatial Resolution: N/A
Swath Width: N/A
Wavebands: N/A
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.
