The 50 megahertz radar located near LaSalle, Colorado, also known as MENTOR, was operated as an Imaging Doppler Interferometer IDI in order to collect radar data. these data were collected from 1825 Universal Time to 2015 Universal Time on 14 October 1988. The data were used to measure winds in the lower atmosphere from less than 1 kilometer up to approximately 11.25 kilometers. The raw data wre transformed from time domain to frequency domain so that the IDI technique could be employed. The number of returns decreased with altitude, as did their radial distance off-zenith. Filters were developed to reject points that did not meet certain criteria, and then algorithms were developed to derive wind speeds and directions.
