Short summary
Cloud optical parameterizations (COPs) in Radiative Transfer for TOVS are evaluated by comparing observed and synthetic visible satellite images. The optimal COP for liquid water cloud is parameterized in terms of effective diameter (Deff) and the COP for ice cloud developed by the Space Science and Engineering Center, with Deff for ice cloud parameterized in terms of ice water content and temperature. The findings will benefit the remote sensing and data assimilation community.
