AB: Computations of cloud characteristics and of all radiation products from the ISCCP radiance data sets require different ancillary data, describing the state of the atmosphere and of the surface. The most important ones describe here the surface skin temperature and albedo and their temporal changes, and also the vertical structures of clouds and the atmosphere. We discovered here "trends", which are primarily caused by incorrect data handling. The final results on the vertical radiative flux divergence show an apparent trend. Thus all radiation products of the ISCCP covering now the period from mid. 1983 to the end of 2005, must be recalculated. Also the SRB products must be re-done, since they are based on the ISCCCP cloud information.
