These files contain a routine which will compute meteorological true winds (direction from which wind is blowing, relative to true north; and speed relative to the fixed earth) when given a set of five arrays of equal length and the zero-line reference (zlr).
| "hd" | --the direction the bow of the vessel is pointing (heading -- referenced to true north) |
| "crse" | --the course toward which each vessel is moving over the ground |
| "cspd" | --the speed of each vessel over the ground |
| "wdir" | --the wind direction measured by the anemometer (referenced to the zlr on the ship) |
| "wspd" | --the wind speed measured by anemometer |
