Detection of snow/ice in the GEO NWCSAF cloud products


Gaëlle Kerdraon presents the algorithm of snow/ice detection in the cloud mask and cloud type products of the NWC-SAF and shows some examples.


The first step of the cloud detection during day, is the snow/ice detection on the ground or at the sea surface. The talk will give details of the flag snow/ice in the cloud mask and in the cloud type. The algorithm will then be presented and illustrated by a recent example. The importance of this snow/ice detection will be pointed out for a good cloud detection. Finally, we will explain the limitations of this flag snow/ice.
