AB: The interactions of aerosol and cloud, and their effects on radiation are complex; many aspects are poorely understood. The complexity is due to the aerosol-cloud interaction mechanism which takes place at smaller spatial scales. Existing parameterizations of this effect are derived using idealized cloud dynamics, aerosol composition and size distribution. However, satelite retrievals of cloud microphysical properties from the Moderate Resolution Imaging Spectroradiometer (MODIS) provide some insight into this mechanism. In our study we will use the information from satelite retrievals and construct a multilayer cloud-aerosol interaction model to study the effect on surface radiation. The results will be compared with satelite measurements and available cloud-aerosol interaction models.
