An astronomical observatory located below the urban inversion in Oakland, California has been recently used as a remote sensing facility for detection of urban aerosol and molecular pollution and transport analysis. These measurements were made with a sixteen element photodiode array close to the focus of a twenty inch refracting telescope detecting visible light extinction and refraction from stellar and artificial light sources. Atmospheric transport was determined by using the time lagged covariance of the scintillation from artificial light sources at several diode separations to determine the space averaged winds which were subsequently included in a wind field model of the Bay Area including topographical effects. The results of this study demonstrate the compatibility of remotely sensed spatially averaged wind measurements as input data to mesoscale models for interpretation of pollution transport.
