Does anyone know the correct procedure for AWS sensors covered by
Snow. The Observers Handbook states for Grass Min thermometers the
instrument is placed on top of the snow cover and for Concrete Min
thermometers you sweep clear the concrete slab. However what is the
procedure for AWS Grass and Concrete Sensors? Do you clear the snow
and leave or clear the snow and clean thre sensor? At present mine are
caked in snow/ice, I've brushed off the loose stuff but left the rest
as I don't want damage the sensors.
