Improved estimates of nitrogen oxides (NOx) and carbon monoxide (CO) emissions through multi-species and multi-sensor chemical data assimilation — Improved estimates of nitrogen oxides (NOx) and carbon monoxide (CO) emissions through multi-species and multi-sensor chemical data assimilation
Over the past two decades space agencies around the world have made considerable investments in satellite instruments to measure the changing composition of the atmosphere. We now have a broad range of space-based measurements of atmospheric composition. This project will integrate observations from different satellite instruments to better quantify surface emissions of CO and NOx, which are harmful atmospheric contaminants. Atmospheric CO and NOx are also precursors of tropospheric ozone (O3), which is a harmful pollutant and a powerful greenhouse gas.
