What Do I Need

Well... You need a rain gauge! And a good place to put it.
Because CoCoRaHS is not only statewide, but national, we strongly prefer everyone to have the same kind of gauge, to better allow comparison of measurements.

We use a 4"-diameter plexiglass gauge that looks like this:

You can purchase a rain gauge from either of these two companies...

WeatherYourWay.com or AmbientWeather.com These are the same gauges, but at $25 they cost a bit more shipping and profit, I imagine.
