Optical scintillometry over a long elevated horizontal path

摘要

Abstract: We report scintillometer measurements for near-infrared propagation over a 51.4-km path, at an average altitude of 760 m over mountainous desert terrain. We present time series and histograms of normalized irradiance variance and path-averaged C$+2$/$-n$/ values. We compare the results with an average vertical C$+2$/$-n$/ profile constructed from past balloon measurements. We also present preliminary results on the temporal power spectra of normalized irradiance.!6
