There is a Vue station a couple of miles away from me, that is mounted high up for the wind, i keep asking myself, whos temp data
would be more accurate when the sun is out, the Vue’s or mine that’s only mounted at about 4ft in a 2x fan assisted shield.
Is there any difference in temp from say 1m to say 9m, if not, then why does the met have a standard height? I believe there is a difference, i.e.
radiated heat from the ground dissipates the higher you go, i believe the met Stevenson screens are about 4ft high’ish? so around body height?
so they would get more radiated heat from the ground than say a Vue mounted at 8 or 9m
I have a point here honest, my temp sensor reads about 1C higher later in the day when the sun is out than the Vue station and the Metar at
Lakenheath, i aint sure how the Metar station is situated but i bet its higher than the standard. The vue is about 2miles as the crown flies and
the Metar is prob about 4 miles, so we aint exactly next door, but, its my station that WU removes from the map cause its over the average in
my area
My sensor is calibrated to a sensor Mick sent me and he calibrated that to one of his that he knows is accurate, i also believe that my shield is working
very well, its very well insulated and the 2 fans are drawing a constant airflow over the sensor. The only issue could be from that lack of airflow in my
garden, 6ft high fencing all round and a bungalow, not a tiny garden though. There is some eddying, i can see it with my e-cig clouds, but i would have
thought that the 2x 4k rpm fans would, oh and i have also made a point of letting the grass grown longer around the sensor area, there is a vast
difference in radiating heat from short grass about 1 inch compared to say 3 inches, when its shorter the grass and ground heats up more than when its longer, i believe the grass part is in the met standard too somewhere…
Am i trying to be too hard, after all its only a personal station?
