Abstract

Data from the ScaRaB radiometer flown on board the Meteor-3/7 satellite were first employed for validating and correcting a TOA Earth radiation budget product generated from GOES-7 and the latter was then combined with ground radiation measurements for addressing the effect of clouds on atmospheric absorption of solar radiation. By virtue of comparison between coincident and collocated radiative quantities derived from ScaRaB and GOES sensors, it was found that GOES calibrations for both visible and infrared window channels appear to be adequate, but narrow to broad-band conversion of short-wave measurements suffers systematic errors. After correcting this problem, the cloud radiative forcing at the top of the atmosphere (TOA) and at the surface were derived from space- and ground-based measurements made during the US Atmospheric Radiation Measurement (ARM). The ratio of the two forcing terms is in excellent agreement with that determined by radiative transfer models, in contradiction to the recent claim of cloud absorption anomaly.
