Mean Conditions and Turbulence Statistics at Vandenberg AFB, California,

Pagination or Media Count:
This report describes the results of a one-year program to gather meteorological data at Vandenberg AFB, CA. The purpose of the program was to obtain data that would allow characterization of the mean flow and turbulence in complex terrain. One full year of data, 24 hours a day, was obtained so that the full range of meteorological conditions at the site would be experienced and to establish statistical validity. The principal goal of the study is to characterize the turbulence, providing a data base for modeling diffusion in complex terrain. Immediate applications being addressed are Space Shuttle exhaust hazard, site specific diffusion at Vandenberg, and generic features of flow and turbulence in complex, coastal terrain. Because the data may ultimately be used for modeling a wide variety of situations, such as continuous plumes, burst releases, rocket exhaust, the data acquisition procedures must be well designed. Specifically, sampling must be done so that the full range of the turbulence spectrum that is important for all types of diffusion is acquired. The purpose of this report is to describe the status of the data that has been obtained and to outline how to use it. Auxiliary data has been obtained and several analyses have been performed. These are also described.
