[wxqc] Calibrating anemometers

[Victor Engel]

I've got a wireless unit, so it can operate on batteries. I calibrate my
speedometer regularly. That's easy to do with a stopwatch and mile markers.
But there are complicating factors with using that method: you have to add
local wind speed, which of course is exacerbated by traffic. Additionally,
the car itself would affect windspeed.

I do have a sunroof, so I could bring the anemometer on a pole and elevate
it above these complicating features and drive down an empty road in calm
weather....
