Abstract:

The correlation of meteorological events such as the jet stream, gravity waves and boundary layer circulation with the optical turbulence parameters, the transverse coherence length r sub o and the isoplanatic angle is essential for interpreting and forecasting imaging and laser systems performance. In support of the United States Air Force Relay Mirror Experiment, the Naval Postgraduate School performed a series of six site characterization measurements near Kihei, Maui, during August 1987 to July 1988. Spatial and temporal summaries of atmospheric events corresponding to the optical remote sensor data are presented using meteorological data from the National Weather Service Radiosonde Observation stations, synoptic charts, GOES-WEST infrared satellite images, and four Kihei, Maui rawinsonde datasets. To quantify the correlation between optical turbulence measurements and meteorological phenomena, four methods of calculating C square T from rawinsonde data were investigated. Results show that existing rawinsonde systems are inadequate for direct C square T calculation. However, moderate improvements in the vertical resolution, the temperature resolution and probe response time, will allow direct calculations of optical turbulence parameters from rawinsonde data.
