Abstract:

The algorithm for determining cloud optical depth and cloud particle effective radii from MSU-MR daytime measurements on-board the Russian meteorological satellite Meteor-M No. 2 is presented. It is based on the physical principles of using the reflectance at 1.6 and 3.7 mm. The algorithm results are compared with the results of the algorithm developed for the AVHRR radiometer. The comparison shows that the cloud parameters retrieved with the algorithm suggested are within the acceptable limits of accuracy.

Keywords:
