My Ambient WS 5000 sensor has routinely failed since installation 4 weeks ago with respect to the wind vector QC parameters on Gladstone/MADIS due to L3 Spatial Consistency. All other sensor readings pass perfectly. That said, I'm assuming that it is due to the fact that the ultrasonic wind sensor is located only 3.21 meters (7') above ground level and situated next to an open field 25' away from my two story barn. Given that the recommended siting requirements for my sensor is 3-4 x the height of my barn or 75'-100' away from the structure at a recommended height of 33', I acknowledge the failure as being due to my stations location. That said, I re-calibrated the wind speed gain on my console from 7' to 33' using 1.41. But now my question after this long winded preface.... why bother to recalibrate wind speed at all when 1) it won't affect the wind vector failure, and 2) why should I care about the wind speed at 33' when I'm only 5'10?
