 |WindSpeedMult=1
-|Multiplier by which measured Average [[Wind_measurement#Compensation|Wind Speed]] to be corrected.  Officially in UK the wind speed is measured with sensors at 10m above ground level.  If your sensor is not at 10m AGL then a correction multiplier should be applied using the following formula ''V10/Vh = 1/(0.233 + 0.656*log10(h+4.75))'' where "h" is your sensor height in meters.
+|Multiplier by which measured Average [[Wind_measurement#Wind_Speed|Wind Speed]] is to be corrected (default=1).
-e.g. if your anemometer is 5m off the ground, V10/Vh comes out at 1.134
