Abstract
The Geostationary Earth Orbit (GEO) provides a unique opportunity of monitoring tropospheric pollutants on the regional scale. Thermal InfraRed (TIR) observations (from about 620-2300 cm-1) have two advantages over other spectral domains: firstly, day/night observations are possible; secondly, numerous molecular species can be observed simultaneously. However, the sensitivity of TIR observations may be a critical point for the geostationary orbit geometry. In this study, we present a feasibility study for TIR pollution observations in GEO conditions. The capabilities of measuring the tropospheric abundance of ozone (O3) and carbon monoxide (CO) are investigated. Limitations of the sensor sensitivity are also discussed.
