That is an odd graph of wind direction. I looked over a one-year plot of

in a gorge where the wind almost always blows east or west, occasionally
from the south, almost never from the north.

Is there some way you could make your database available to me? Perhaps put
it on a Google Drive, or FTP server? I'd like to take a closer look.
