Short summary
This study attempted to explain why deep convective clouds (DCCs) over the western Pacific are generally darker than those found over tropical African and South American land regions over the tropics. It was noted that smaller ice water path of the DCC over the western Pacific is mainly responsible for smaller reflectivity there. Findings further suggest how DCC criteria are set up for selecting the targets for the solar channel calibration.
