Dr. Jedlovec has spent most of the last 20 years developing and evaluating algorithms to retrieve geophysical parameters from remotely sensed aircraft and satellite measurements for regional climate studies and weather forecasting applications. His early work as part of the VAS Demonstration program emphasized the importance of the new water vapor channels on the GOES geostationary satellites and their application to atmospheric research. The limitations of passive infrared remote sensing for temperature and moisture profiling were evaluated and documented in the peer-reviewed literature. For his dissertation, Dr. Jedlovec developed two unique methods for the retrieval of bulk water vapor estimates that are applicable to both aircraft and satellite observations. One method, the Physical Split Window technique, has proven to be a simple, highly accurate method of retrieving integrated water content and land surface (and sea surface) temperature with just two channels of information. This technique has been applied to the GOES Imager and Sounder data in an operational environment at NASA’s Global Hydrology and Climate Center for the last 3 years, and most recently to real-time MODIS data from NASA’s Aqua and Terra satellites. Real-time LST and SST data from GOES and MODIS are being incorporated into regional numerical models to prescribe the partitioning of available moisture from the surface without elaborate surface parameterizations. Most recently, Dr. Jedlovec is leading an effort to transition the use of unique NASA EOS satellite data (from MODIS and AIRS instruments) into the Huntsville NWS Forecast Office in order to improve aviation and public weather forecasts issued by that office.

Dr. Jedlovec is a member of the American Geophysical Union, American Society of Photogrammetry and Remote Sensing, and the American Meteorological Society. He has published numerous peer-reviewed papers on satellite remote sensing in a variety of journals.
