Important: EddyPro requires the offset with respect to geographic north as two
pieces of information: The offset with respect to geographic north and the mag-
netic declination. Currently the software does not provide an entry for magnetic
declination. For the best results, enter the North Offset to magnetic North. This
will create small differences in the wind direction between EddyPro and
SmartFlux results (a constant offset equal to the magnetic declination), but the
flux results will be the same, if all other settings are the same.
Height (m) (mandatory) :
Sonic anemometer height above the ground, in meters,
measured to center of the anemometer sample volume.
Configuring the Analog Anemometer Inputs
When the anemometer is connected to the LI-7550 (using the analog signals), the
Inputs
dialog must be configured in order to scale data from the anemometer prop-
erly.
IMPORTANT: It is mandatory to specify the scaling of the wind speed meas-
urements to allow EddyPro Software to read these values and calculate fluxes.

s
(or SOS) output from the anemometer.

are the units that will be logged with the variable.
l
Label
is logged in the data and metadata. It identifies the
variable.
