The variable effect of clouds on atmospheric absorption of solar radiation
Article Abstract:
The validity of the general circulation model predictions of climate change has been questioned because of a consistent discrepancy between the predicted and actual solar radiation absorbed by clouds, called the cloud absorption anomaly. This discrepancy is based on the effect of clouds on atmospheric absorption of solar radiation, a ratio that may be influenced by other factors than just clouds, creating the cloud absorption anomaly. Research does not prove that the anomaly does not exists, but does suggest that it is not as significant as generally believed.

Clouds, contrails and climate
Article Abstract:
Recent studies have aimed to assess the atmospheric impact of aircraft exhaust. Satellite observations during NASA's SUCCESS project show that persistent contrails can evolve into extensive cirrus clouds. A large amount of ice-supersaturated air must therefore exist in the upper troposphere that is able to produce cloud in the presence of nucleating aerosols. The questions of how often contrails sawn extensive cirrus clouds and how large and long lived they are, are still unanswered.

Inside history on droplets
Article Abstract:
Issues concerning the process of freezing which creates the ice particles in te upper tropospheric clouds are discussed. Particular attention is given to laboratory experiments helping to assess the impact on weather of upper-tropospheric cloud ice particles.
