Synergetic cloud fraction determination for SCIAMACHY using MERIS

22 February 2011

A newly developed algorithm for determining a more accurate geometric cloud fraction for SCIAMACHY ground scenes at nadir using MERIS (MEdium Resolution Imaging Spectrometer) spectral measurements was presented. This has been called MICROS, (MERIS cloud fraction for SCIAMACHY).

The MICROS algorithm has been developed by the team in the University of Bremen to determine an accurate geometric cloud fraction for a SCIAMACHY ground scene at nadir using MERIS RR spectral measurements. For the classification of the MERIS pixels, in either clear or cloudy, a set of thresholds and constraints has been utilized.
