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
