Hi @gliska15 we’re happy you found us as well. Welcome! Can you provide a link to the WF station to which you are comparing? As you might know, wind fields vary massively due to the dynamics of the exact environment in which a station is sited. In most cases, comparing two stations which are not exactly co-located is like comparing apples to oranges (unless both stations are calibrated professional-grade equipment, sited by a meteorologist, both mounted at 10m height with no obstructions).
That said, when comparing a highly sensitive sonic anemometer (like the WF SKY) to a traditional spinny cup anemometer placed in the exact same location — one will notice a wider range of measured wind variance as the sonic is not affected by inertia like the spinny cups. When the wind drops, the spinny cup anemometer can over report measured wind as the it takes time for the momentum to dissipate. Further, due to friction in the spinny cups, the minimum cut-in speed can be much higher than a sonic. Both of these factors will influence the avg : gust ratio that you mention.
The measurement nuances noted above are far less significant contributors versus micro-scale disturbances the wind fields. When comparing wind data for two home stations — it’s only relevant if the stations are in the exact location (within 3 feet of each other) and sampling at a similar interval.
We love comparisons and data-centric analysis. Hope to hear more from you.
