The general idea is that rain gauges should be as flush with the ground as
possible to ensure that the catch is affected as little as possible by the
wind. Just to test this I put three idenitical TBR (Youngs) gauges at
rim-heights of 40cm, 100cm and 160cm above the ground. From 12/11/07 to
29/01/08 they collected 210.4, 213.2 and 216.5 mm respectively. Um...

Do the 3 gauges record identical amounts if they are all placed at the
same height above ground? Could the differences just be due to
instrument calibration?
