CEOS EO HANDBOOK – INSTRUMENT SUMMARY - CO2I -
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.
