The atmospheric radiation process is a key process to understand significant impacts of aerosols and clouds on the earth's climate system. This talk will overview several important issues involved in the process, such as direct and indirect effects of aerosols to generate positive and negative radiative forcings to partly enhance and cancel the positive greenhouse gas radiative forcing in the global warming phenomenon. The cloud life cycles also can be studied from radiation measurements of the ground-based and satellite sensors. There are, however, still large uncertainties in estimate of their effects, that I like to touch on for identifying important future research targets to reduce the uncertainty.
