Research Interests

An understanding of infrared molecular lineshapes is crucial for satellite observations of global climate change. We study molecular lineshapes of atmospheric and planetary molecules using tunable diode laser spectroscopy and high resolution Fourier transform spectroscopy. Current investigations include an examination of the effects of line mixing and the finite duration of collisions on CO2 and H2O spectral lineshapes. We are particularly interested in developing models of rotational relaxation in nearly degenerate CO2 vibrational states that are split by Coriolis interactions. Our results are used in the analysis of data taken with the ATMOS experiment which flies on the space shuttle and the recently launched Upper Atmosphere Research Satellite, both of which study stratosphenc chemistry.

A major part of our research is involved in the development of a new satellite instrument (Atmospheric Infrared Sounder - AIRS) for the measurement of long-term global change. We are participating in the instrument design, and developing algorithms for the retrieval of atmospheric parameters from the satellite measured radiances. We are presently studying the utility of artificial neural networks for one of these algorithms. We are also developing algorithms to measure global CO concentrations using AIRS. This instrument, which is slated for launch in the year 2000, may provide the first unequivocal measurement of global climate change. Our laboratory studies of molecular collisions will play an intimate role in the analysis of the data from AIRS.
