Abstract:
The role of clouds is of highest priority in many global change programs due to their radiative effects in both the solar and thermal regions of the electromagnetic spectrum. In general, clouds have opposite effects in these two spectral regions. The net effect for the Earth-atmosphere column is the difference between these two large forcings. The aim of this paper is to compute the radiative properties of a homogeneous cloud layer using the column integrated extinction coefficient called the optical depth. The dependence of the albedo and emittance of the liquid water path was also studied. The results show the structure and the microphysics of the cloud affect the mean properties, substantially.
