Joint assimilation of satellite aerosol, cloud, and precipitation observations in numerical models to support climate and hydrologic applications (Joint-Assimilation)
Start date: 01 May 2008, End date: 30 Apr 2012 PROJECT  FINISHED 

Clouds and their interaction with radiation represent one of the largest uncertainty in climate and weather prediction. This is because clouds result from processes and depend on variables such as aerosols that have not comprehensively observed until recently. The advent of the satellite technology made possible the continuous monitoring of clouds and related variables from space. Our primary research objective is the use of existing satellite aerosol, cloud and precipitation observations to gain insight into cloud processes and their impact on climate and weather. Specifically we intend to assimilate satellite observations into a state of the art cloud-resolving atmospheric model. This will facilitate a better analysis of the interaction between clouds and large scale processes and allow for the development of better cloud microphysical schemes. Based on the analysis, the impact of aerosol of climate and weather will be rigorously assessed. The project will also facilitate the re-integration of Dr. Mircea Grecu into an European Research Institution. The Hellenic Center for Marine Research is commited to support this re-integration by offering Dr. Grecu a four-year long appointment.
