The principal focus of my research is the investigation of the climatic effects due to radiatively active gases, aerosols and clouds in the atmosphere. Radiative transfer models of high precision have been developed to determine the forcing exerted by different species upon the surface-atmosphere system. Currently, the perturbations due to changing concentrations of greenhouse gases and aerosols since pre-industrial times are being examined. Numerical models of the atmosphere are used to study the transport and transformation of the species, and to assess their climatic impacts.
Another major research aim is to understand the hydrologic cycle in the atmosphere, in particular the processes governing the distribution of water vapor, and the formation, maintenance and dissipation of clouds. The physical properties of aerosols and clouds play a significant role in the radiative balance of the planet, and their accurate evaluation is essential for resolving issues concerning global change. Mathematical models of varying complexity are employed to study different aspects of the global cloud-climate interactions problem. This effort is aided by diagnostic analyses of data drawn from a variety of meteorological and satellite observations.
