CEOS Instrument: Michelson Interferometric Passive Atmosphere Sounder

Agency: ESA
Mission: Envisat
Type:Limb-scanning IR spectrometer
Description:Data on stratosphere chemistry (global/polar ozone), climate research (trace gases/clouds), transport dynamics, tropospheric chemistry. Primary/secondary species: O3, NO, NO2, HNO3, N2O5, ClONO2, CH4
Spatial Resolution: Vertical resolution: 3 km, vertical scan range 5 - 150 km, Horizontal: 3 x 30 km, Spectral resolution: 0.035 lines/cm
Swath Width: N/A
Wavebands: MWIR-TIR: between 4.15 and 14.6 ?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.
