- Sewanhaka High School, Floral Park, NY (1973). B.S. Physics - State Univ. of New York at Albany (1978). M.S. Atmospheric Science - University of Oklahoma (1986). - Passed Ph.D. qualifying exam.
1986 to Present: Senior Research Associate - NOAA/OAR/ESRL* (Earth System Research Laboratory)
Extensive development and implementation of meteorological analyses of wind, clouds, temperature, and microphysical variables for the Local Analysis and Prediction System. A variety of remotely sensed and in-situ data is ingested, quality controlled, and merged in the analyses. The analyses are used for initializing NWP models and are displayed on workstations for nowcasting. Installation of analysis systems at ESRL and other government agencies and private companies. Satellite image processing algorithms, including photometric correction that depends on viewing geometry. Ray-tracing algorithm was developed to simulate realistic all-sky images from NWP model analysis/forecast output. This operates from vantage points between ground level and outer space. The full-color simulated images are being compared with actual imagery from all-sky cameras and images from the DSCOVR satellite. This serves the purpose of communication of model output, model validation, and can act as a forward model to assimilation of images into models. Image processing to produce global planetary, meteorological, and geophysical maps using IDL and other display software for NOAA's Science On A Sphere TM (SOS). Gave numerous SOS presentations. Meteorological workstation and World Wide Web display software. Development of radar Doppler velocity de-aliasing algorithm. Testing and evaluation of algorithms to be run on the Next Generation Weather Radar (NEXRAD). 40+ journal and conference publications. CIRA/LAPB personnel supervisor.
