Paper Abstract

A newly-developed Atmospheric Turbulence Measurement and Observation System (ATMOS) was equipped with multiple apertures, allowing the phase structure function to be determined experimentally. Data was obtained with the ATMOS under two conditions: (a) over a horizontal path with a laser source, and (b) from near-vertical viewing of stellar sources. This data was compared to measurements of the refractive index structure parameter (Cn2) obtained from scintillometers, spatially separated temperature probes, and anemometers. The existence of the Kolmogorov spectrum of turbulence during the measurement period will be discussed as well as the relevance of the results on the transverse coherence length, r0. The optical arrangement, as well as data collection and analysis methods, are also outlined.
