Rainfall comparison
In late February 2009 I was lent a standard rain gauge.
Up till then I had always relied on the automatic weather station's
tipping bucket gauge to give the rainfall. But February brought snow,
which was hard for the AWS to cope with. So I got the standard rain
gauge, which managed, with some help from me in melting the snow it had
gathered, to give real figures.
Part of the deal for the loan of the rain gauge was that I should
compare the output of the AWS and the gauge. This revealed substantial
differences between the outputs, the AWS showing less precipitation
than the standard gauge. It occurred to me that it might be of interest
to others in the field of weather data collection to see the comparison
I have been making since the beginning of March 2009. So I give the
figures for 2011 below.
