CEOS Instrument: Scanning Imaging Absorption Spectrometer for Atmospheric Chartography




Instrument:SCIAMACHY
Agencies: ESA [Primary]
 DLR
Mission: Envisat
Status:Operational
Type:High-resolution nadir-scanning SW spectrometer
Description:Measures middle atmosphere temperature. Provides tropospheric and stratospheric profiles of O2, O3, O4, CO, N2O, NO2, CO2, CH4, H2O, and tropospheric and stratospheric profiles of aerosols and cloud altitude
Spatial Resolution: Limb vertical 3 x 132 km, Nadir horizontal 32 x 215 km
Swath Width: Limb and nadir mode: 1000 km (max)
Wavebands: UV - SWIR: 240 - 314 nm, 309 - 405 nm, 394 - 620 nm, 604 - 805 nm, 785 - 1050 nm, 1000 - 1750 nm, 1940 - 2040 nm and 2265 - 2380 nm
Technology: High-resolution nadir-scanning SW spectrometer
Description: Spectrometers to cover bands in UV, Vis, NIR and SWIR with spectral resolution typically of 0.1-0.3 %, required for atmospheric chemistry. Earth viewing so as to measure vertical profiles and total columns. Thousands of channels. Spatial resolution typically 2-20 km. Applicable in LEO and GEO.
