Still some snow about surprisingly, thought it would have all melted, happy days!
So my new weather station arrived today, all set up and outside nicely and everything's working, all connected up to the laptop too. However kept the old thermometer from the last weather station out there (that's all that works from my last one) and they are giving quite different readings! The old thermometer (on a fence, facing north under some trees) is reading 3.6C whilst the new one (places on the shed, near the fence and under a tree, quite well sheltered) is reading 2.9C - very interesting to see the two differ, is the new one likely to be more accurate?
