THE NASA CLOUDS AND THE EARTH S RADIANT ENERGY SYSTEM (CERES) EDITION 4 (ED4) CLOUD PROPERTY PRODUCTS HAVE RECENTLY BEEN MADE AVAILABLE FOR PUBLIC USE. COMPARED TO ITS PREDECESSOR THE CERES EDITION 2 (ED2) THE ED4 CLOUD PRODUCTS HAVE BEEN IMPROVED SIGNIFICANTLY IN CLOUD FRACTION CLOUD HEIGHT AND CLOUD MICROPHYSICAL PROPERTIES GLOBALLY. HOWEVER SOME OUTSTANDING ISSUES EXIST SUCH AS DIFFERENT TRENDS OF CLOUD FRACTIONS AND HEIGHTS DERIVED FROM TERRA AND AQUA MODIS OVER THE POLAR AND NON-POLAR REGIONS OCEAN AND LAND AND DAYTIME AND NIGHTTIME AS WELL AS THE CLOUD 3-D EFFECT ON THE CERES CLOUD PROPERTY RETRIEVALS AND THE DEPENDENCIES OF THESE RETRIEVALS ON THE SATELLITE VIEW ZENITH ANGLE (VZA) AND SOLAR ZENITH ANGLE (SZA). ANOTHER OUTSTANDING ISSUE IS THE INCONSISTENT CLOUD PROPERTIES BETWEEN MODIS AND VIIRS. THESE ISSUES NEED FURTHER INVESTIGATION. IN THIS PROPOSAL OUR VALIDATION EFFORTS WILL BE GROUPED INTO THREE OBJECTIVES COMPRISED OF SEVEN TASKS AS FOLLOWS.
