The Great Climate Debate and Our Changing Climate are two articles that reflect the growing concern over the enhanced greenhouse effect (global warming) and how pollutants are harming our environment. It is believed that anthropogenic trace gas concentrations, which has been occurring since the pre-industrial period, is the primary cause of the observed increase in the global mean atmospherics temperature observed over the same period. Atmospheric scientists use global climate models to investigate this issue. The models, however, are limited in their ability to properly represent all the processes in the climate system, and thus produce results with many uncertainties. Cloud processes, particularly those of high clouds, are among the least understood and thus poorly represented processess in climate models. This project is being conducted in support of research to improve the representatin of high cirrus cloud infrared radiative properties in climate models. Specifically, cloud properties derived from aircraft measurements over the Tropical Western Pacific are processed and analyzed for a model validation experiment. The results of this experiment shoud provide further insight into the role of cirrus clouds in climate change.
