MSG/SEVIRI -- Cloud Mask

The following images show that the result of the simple cloud mask algorithm.
Algorithm: Pixels satisfied the following conditions are considered cloud free:

R01 >0 and R02 >0 and T09 > 0 and

R01 < Ref_threshold and

R02 < Ref_threshold and

(max_T09_in_3x3Box - T09) < 2 and

stddev_3x3_R01 <= RUT_threshold and

stddev_3x3_T09 <= TUT_threshold
