IDL Codes for True Winds

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

The following files can be downloaded in the tar file IDL-codes.tar. To view each file individually you may click on the filename in the table.
