I replaced my #CoCoRaHS rain gauge today. After 12 years in the elements the old one was cracking and getting very crazed and impossible to read!

@bud_t It was reported the old style had a slight underreporting error. I’m still using mine but will probably update in a year or two. I’m in CO as well.
@btschumy interesting I did not know that!

@bud_t See the last sentence of the first paragraph here:

I misremembered, the old gauge reads slightly high not low.

A New Rain Gauge Option for CoCoRaHS

A new rain gauge, the Tropo, has been approved for CoCoRaHS use. This is in addition to the original 4" gauge manufactured by Productive Alternatives.
