Impact of 3D Cloud Structures on the Atmospheric Trace Gas Products From UV-Vis Sounders (3DCATS)

Summary

In current atmospheric trace gas retrieval schemes exploiting UV-vis sounder data, clouds are treated in a simplistic way ignoring 3D structures and cloud shadows. In this activity, the impact of such cloud effects on trace gas products is quantified, building on statistical analyses of cloud observational data and on 3D Monte Carlo radiative transfer simulations for typical cases. Improved handling of cloudy scenes and mitigation of related biases is explored and tested on real UV-vis observational data exploiting cloud signatures in collocated imager data.
