A FORTRAN program has been developed for displaying wind direction and wind speed data maps, as determined by the HF Over-the-Horizon Radar. The output products are a grid of wind direction arrows for each range/azimuth radar cell, and continuous contours of wind speed, plotted on a stereographic projection of the Northern Hemisphere about the North Pole by a CALCOMP 565 plotter or compatible CRT display. Data inputted are generated by other programs described elsewhere, and include radar cell latitude and longitude, ambiguous wind direction pairs, and three independent values of wind speed, all of which can be plotted in a number of different combinations.
