Description

The data from the profiler is downloaded and stored at the field site computer (GlacialRidge2, 64:235:73:178:0). Horizontal and vertical winds are computed from the 3 beams. Uncorrected reflectivity, radial velocity, and spectral width data are plotted and stored as images on the field site computer as well. MatLab scripts are run every hour (roughly 15 min after each hour) to process the given data.
