I've had a couple of emails from the PIs about our wind directions.  I found (and hopefully just corrected) a bunch of things, using data from the magnetic boom angle shoots:

  • Entered Vazimuth into csat.dat for all sites.  This is used in R by dat.Vazimuth to generate dat("dir") (that the PIs probably never saw, since we don't plot this or use it in qctables).
  • Corrected dat.Vazimuth to actually return these angles!
  • Entered Vazimuth - 180, which should be the correct angle for the 2D Gill sonics into the dir_gillwo... cal_files.  This is used by NIDAS (and thus statsproc) to generate dat("Dir") in the NetCDF files and used in the weather plots.
  • Restarted both statsproc processes to pick up the change to the 2D sonics.

Hopefully, things will look better now!

P.S., everything had to be revisited!!

  • For CSATs, Vazimuth is "the direction relative to true north, straight into the array from the un-obstructed direction, minus 90 degrees.", so nominally 45 degrees for this project.
  • dat.Vazimuth still needed work.  Now it functions correctly.  Don't know how it got so far wrong.
  • Found that the 2D sonic at s4 was mounted on the opposite side of the mast, so had to add 180 to its dir_gillwo... offset
  • Restarted statsproc yet again
