These fields are important because they are
used to determine some flux corrections. See the EddyPro

instruction manual or
online help for more information.
Wind data format (optional) :
From the three axis velocities, the wind speed is cal-
culated, and output as either signed U, V, and W, as Polar and W, or as raw velocity
values. The units of output are set during the anemometer configuration. Choose
the wind data format from the menu:
l
U, V, W (some Gill anemometers): U is the direction aligned with the north
spar. V is the direction 90° counter-clockwise from the N/Reference spar. W is
vertical.
l
Polar, W - The wind speed in the UV plane, with direction in degrees clockwise
from 0 to 359°, with respect to the Reference spar (normally aligned to North).
Note: This option is not supported for Gill anemometers.
l
Axis velocities - Raw velocity values for U, V, W.
North offset (°) (mandatory) :
Offset, in degrees (0-359°) from which the Reference
spar/axis or orientation of the anemometer varies from geographic/magnetic north.
