Currently there are seven wind measurements reported from the Campbell logger.
| minimum_wind_speed |
| wind_gust |
| Scalar averaged wind speed, wind_speed_sc |
| Vector averaged wind speed, wind_speed_ve |
| Unit Vector averaged wind direction, wind_direction_uv |
| Vector averaged wind direction, wind_direction_ve |
| Unit Vector averaged wind direction standard deviation, wind_direction_stddev_uv |
| Vector averaged wind direction standard deviation, wind_direction_stddev_ve |
The quantity wind_speed is being defined as the scalar speed. Wind direction is being defined as the vector average. Wind speed is taken as is. There are two simple offsets that may need to be applied to the wind directions after they are reported, magnetic variation, and the ad hoc offset if a compass was not properly calibrated pre-deployment.
wind_speed_sc
wind_direction_uv
Magnetic variation, a global attribute in the NetCDF file, global::magnetic_variation
Ad hoc offset (hopefully this is zero).
