CEOS Instrument: Improved Limb Atmospheric Spectrometer

Agencies: MOE (Japan) [Primary]
Mission: ADEOS
Status:No longer operational
Type:Limb-scanning IR spectrometer
Description:Measures minor trace gas species at high latitudes, in the altitude range 10 - 60 km (O3, CH4, NO2, N2O, H2O, CFC11, HNO3, CIONO2, N2O5, aerosols, temparature, pressure)
Spatial Resolution: 700 m
Swath Width: 1400km
Wavebands: NIR (~0.75 ?m - ~1.3 ?m)
Technology: Limb-scanning IR spectrometer
Description: Spectrometer operating in MWIR and TIR 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. Many thousands of channels. Spatial resolution typically 1-3 km vertical, 300-500 km horizontal. Applicable only in LEO.
