Rain Accuracy Due to Melting Snow and Frost
Posted: Thu 21 Jan 2016 7:52 am
What is the proper procedure in weather recording to deal with rain recorded due to melting snow and/or frost, please?
During the current cold snap, my WH3080 station has shown 0.3mm of rain (the minimum it can register) on a couple of days when there hasn't been any rain, but following a sharp frost. I assume the recording has been due to the frost melting on the sensor.
I have read several threads where others have spoken about this, including one who attempted to overcome it by using a heater (not sure how you do that and how it works though), but none that say how it should be shown, or referred to, in our recorded data.
