Measurements of Refractive Index Structure Function C2N and Aerosol Size Distribution at Chesapeake Bay.

Abstract

Measurements of (C sub N) square using fine wire thermal probes were obtained on a 35 m tower located between the cliff face and the shoreline at Chesapeake Bay, MD. The data collected have shown, using long averaging times, that the -4/3 height dependence of (C sub N) generally still applies in the vicinity of the cliff face with light winds coming from either over the cliff or over the water. The aerosol size distribution data revealed very little change in the distribution with height. Over the 0.15 to 0.75 micrometers radius range both bi-modal log-normal and power laws described the shape of the distribution curves. Keywords: Optical propagation; Turbulence. (Author)
