The Cloud Screening Processor is the second of three main modules within the MERIS/(A)ATSR Synergy toolbox. Its purpose is to add various bands (i.e cloud flags) to the colocated MERIS/(A)ATSR L1b product obtained from the preprocessor. The output product from the cloud screening shall be used as input for the third module (aerosol retrieval and atmospheric correction).

The user interface for the Cloud Screening Processor is represented by one main dialog, which consists of the following components:
