Stratospheric and tropospheric chemistry-transport models. Regridding of fields.
Mr. Stephen D. Steenrod received a B.S. with a dual major of Atmospheric Science and Mathematics from the State University of New York at Albany in 1981 and a M.S. in Meteorology from the University of Wisconsin - Madison in 1983. His graduate work investigated diurnal variation of oceanic convection. He then came to Goddard Space Flight Center in the Oceans and Ice Branch, working on a model of the wind driven ocean circulation. After a few years he moved to the Atmospheric Chemistry and Dynamics Branch, where he continues to work. In this branch he has worked mainly with the analysis and coding of the 3D Chemical Transport Model. The last few years he has been working on the Global Modeling Initiative (GMI), which is part of the NASA Modeling Analysis and Prediction (MAP) program. GMI investigations support the development and integration of a state-of-the-art modular 3-D chemistry and transport model (CTM) that includes full chemistry for both the troposphere and stratosphere. The GMI model is involved in assessment of anthropogenic impacts, such as those from aircraft, future changes in atmospheric composition, and the role of long-range transport of pollution. The GMI model serves as a testbed for different meteorological fields, emissions, microphysical mechanisms, chemical mechanisms, deposition schemes, and other processes determining atmospheric composition, both gas-phase and aerosol.
