  1. Mean heading reflects the bearing from the first GPS measurement toward the last GPS measurement in each run. Wind speed and direction (heading; note that this is the direction the wind vectors are following, not “blowing from” as is customary) are coarse-scale regional estimates based on the NCEP’s Global Forecast System, as described in methods
