Abstract

Initial data for the current and ongoing experiment to measure and possibly predict the horizontal turbulent strength, C²_N , of the atmosphere above the Magdalena Ridge Observatory Interferometer (MROI) is presented. C²_N is a representation of the atmosphere’s ability to transport scalars and is measured using a set of Kipp and Zonen Large Aperature Scintillometers (LAS). LAS Calibration data as well as initial test data are presented and analyzed. Correlation techniques are used to determine the optimal method of C²_N calculation from the first generation LAS. A 19-day test over the array site was conducted and analyzed using both Fourier and wavelet analysis and filtration. Frequency analysis showed few periodic features due to the quasi-periodic nature of the signal.
