[wxqc] rain gauge question

[Victor Engel]

I'm new to the electronic weather station business, but it seems to me that
a Tru-Chek gauge will not be a very good way to calibrate. It's surface area
is very small and consequently the precision is low.

Siting is also very important. An accurate rain gauge is only as accurate as
the location/shelter where it's placed.

Reading up on your gauge, it looks like it works by funneling all rain into
a drop counter. I suppose this would be dependent upon the cleanliness of
the lens that senses the drops as well as the surface tension of the water.
I bet if you washed your gauge with Dawn dishwashing detergent and didn't
rinse completely, your gauge would be way off. I wonder how much the surface
tension of rainwater actually varies....

I'm just brainstorming here....
