Dr. Waight joined MESO in October of 1987 after completing his Ph.D. in atmospheric science at the University of Wyoming. His first three years at MESO were spent in Huntsville, Alabama where he worked on a project funded by the NASA Marshall Space Flight Center to study the role of moist convection as a mechanism for interaction between the mesoscales. In this project he analyzed meso-b scale data from the COHMEX field experiment and compared it to mesoscale simulations from the MASS model for the purpose of improving the parameterization of moist convection on the meso-beta scale. After spending 3 years in Huntsville working on this project, Dr. Waight relocated to MESO's Troy, New York office in December of 1990 to assist in the development of MESO's real-time operational mesoscale modeling system. Dr. Waight was elected Vice-President of MESO in September 1992.
Prior to joining MESO, Dr. Waight was a graduate student at the University of Wyoming where he participated in the Terra Nova Bay Katabatic Wind Study in Antarctica. In this project he prepared automatic weather stations for deployment at Terra Nova Bay and flew by helicopter onto the Ross Ice Shelf to repair stations. In 1984, Dr. Waight participated in the Sierra Cooperative Pilot Project in California. He served as flight technician on the Wyoming Super King Air research aircraft and operated on-board data systems with real-time display capabilities. As part of this project he collected ice crystal slides and processed, archived and analyzed data after flights. During 1981 and 1982 he was employed at the Institute of Environmental Studies at Baylor University where he archived solar and meteorological data on microcomputers.
Dr. Van Knowe joined MESO in February 1997 after 24 years as a meteorologist for the Air Force. During his Air Force career, on world-wide assignments, he worked as a weather observer, then a forecaster, and finally as a research meteorologist. He was Chief of Meteorology at Rome Lab (Rome, NY) from 1990 through 1994. As Chief of Meteorology, he directed the meteorological aspects of all research at Rome Lab which included several modeling and weather radar projects. One such effort involved assisting with tests of the first operational NEXRAD radar for possible enhancements of performance quality during both summer and winter conditions in Upstate New York. He also worked on a joint service team to develop mesoscale analysis modeling capabilities for combat conditions. In addition to his Air Force duties, he served as an Adjunct Professor of Meteorology at Embry Riddle University during this period. In his last assignment before coming to MESO, Inc. he was chief of the modeling and simulation development branch for the Air Force's Combat Climatology Center (AFCCC) at Scott AFB, IL. One of his responsibilities was to direct a project to adapt a dynamical mesoscale numerical weather prediction model for use as a tool to generate climate statistics in data sparse regions. Also during this time, Dr. Van Knowe used the Mesoscale Atmospheric Simulation System model (MASS) to investigate rapid cyclogenesis events for his Ph.D. dissertation at Saint Louis University.
Ms. Price has over nine year of experience with the development and application of cloud-scale atmospheric numerical models. Ms. Price was hired by MESO as a research scientist in November of 1986. As a research scientist she has overseen the application of MESO's TASS cloud model. She has used two and three-dimensional versions of the TASS model to simulate and study a variety of convective phenomena including hailstorms, tropical feeder bands, shuttle exhaust clouds and fire-induced clouds.
Prior to joining MESO, Ms. Price was employed by SASC Technologies from September 1985 to November 1986 where she converted and optimized the two-dimensional TASS cloud model from Cyber FORTRAN vector code to Cray FORTRAN and used the model to simulate nuclear blast clouds. She also assisted in the use of the TASS model to simulate the exhaust cloud from the NASA space shuttle. Before her employment at SASC Technologies, Ms. Price was a graduate research assistant at the South Dakota School of Mines and Technology where she improved the microphysics in a two-dimensional cloud model, evaluated the effects of artificial seeding for a High Plains hailstorm simulation and assessed the ability of a one-dimensional cloud model to predict seeding effects through comparisons with radar data. She was also employed by the North Dakota Weather Modification Board as a radiosonde operator during a summer field project. In this capacity she was responsible for daily radiosonde releases and data reduction. She also operated a WR-100 weather radar and recorded digitized data on magnetic tape.
Ms. Bousquet has ten years of experience in the development of meteorological applications programs and graphical displays of meteorological data on a diverse group of computational platforms including Macintosh microcomputers, UNIX workstations and Cray and Cyber supercomputers. Ms. Bousquet was one of the original founders of MESO and has served as the corporate treasurer and scientific software developer since MESO's incorporation in 1985. Her software endeavors at MESO have included the development of programs to display two and three dimensional static and animated representations of data generated by MESO's mesoscale and cloud scale numerical models.
Prior to her tenure at MESO, Ms. Bousquet was a scientific programmer at SASC Technologies in Hampton Virginia. At SASC Technologies she developed software to generate graphical displays of results from a cloud scale numerical model using the CDC Cyber 205 vector processing supercomputer. Before joining SASC Technologies Ms. Bousquet held the position of data analyst at the Old Dominion University Research Foundation. Her work at the Research Foundation included the retrieval of derived quantities from raw sensor data through the application of the lidar equation and the generation of graphical displays of the processed data.
Mr. Young joined the MESO staff as a research associate during 1991 while completing his M.S. thesis at the State University of New York (SUNY) at Albany. Mr. Young has made significant contributions to the development of the MASS model including the implementation of a new boundary layer modeling scheme and the conversion of the code from a hydrostatic to a non-hydrostatic configuration. Mr. Young also developed most of the data ingestion and initialization modules for the OMEGA model data preprocessor. Prior to joining MESO, he was a graduate research and teaching assistant at SUNY-Albany from September of 1988 through 1991. His principle area of research was in the numerical simulation of cold air damming and frontogenesis along the east coast of the United States. During 1987, Mr. Young was a research assistant at the Atmospheric Science Research Center's Whiteface Mountain Field Station. In this position he collected cloud water samples and assisted in the management and quality control of meteorological databases.
