THE CEOS DATABASE : Missions, Instruments and Measurements
Full Name Integrated CO2 & NO2 Imaging spectrometer Status Being developed
Instrument Agencies COM, EUMETSAT Maturity
Instrument Type Atmospheric chemistry Geometry Push-broom scanning
Instrument Technology High-resolution nadir-scanning SW spectrometer Sampling Imaging
Data Access Open Access Data Format
Measurements and Applications Pushbroom scanning spectrometer to provide relatively high spatial resolution CO2, CH4 and NO2 observations in support of estimating anthropogenic emissions of CO2 and CH4 in Copernicus. In addition, high quality NO2 and solar-induced fluorescence will be operationally delivered.
Resolution Summary 4km2
Swath Summary 250km
Accuracy Summary Co2 precision=0,7ppm, CH4 precision=10 ppb, No2 precision 1.5 10e15 molec/cm2
Waveband Summary For CO2: TOA radiance measures in NIR (747-773nm), SWIR1 (1590-1675nm), SWIR2 (1990-2095nm). For NO2: VIS (405-490nm)
VIS (~0.40 µm - ~0.75 µm)
NIR (~0.75 µm - ~1.3 µm)
SWIR (~1.3 µm - ~3.0 µm)
