Biography

Mikhail Ovchinnikov's current research interests include a wide range of topics in cloud physics, as well as cloud-related aspects of remote sensing, radiation, and atmospheric dynamics. Dr. Ovchinnikov relies on a combination of numerical modeling, in situ, and remote observations in nearly all of his studies, which have three major thrusts: 1) studying individual aerosol and cloud processes, 2) retrieving cloud properties using remote sensors, and 3) developing, testing, and improving modules and parameterizations for atmospheric models from cloud to global scales. Finding new ways to evaluate these models and validate simulation results is always the top priority of these studies.

A unifying theme of several of his projects funded by the Deparment of Energy and the National Aeronautics and Space Administration is the use of an "instrument simulator" concept, in which the model output is used to reconstruct what a specific observing system would detect. The synthetic measurements are then used to evaluate the model and to test retrieval algorithms.
