( However, a rain gage projecting upward above the ground may, in a
more detailed analysis, be seen to have SOME effect on the collected
rain because it disturbs the air flow (wind) and hence the "flow" of
raindrops and this could be a VERY MINOR effect and I guess that
somewhere and at sometime all this has been investigated in great
detail by someone).

There is (was?) something on the MetO site about rain gauges in
exposed locations and how they should be sited and protected. ISTR a
earth ring a few feet from the gauge and possibly the same height as
the guage top. Presumably to try an get laminer flow over the gauge
rather than turbulent from the wind suddenly hitting the gauge and
having to flow around/over it.
