Report Rain and Snow
CoCoRaHS volunteers measure precipitation with a simple backyard rain gauge and report it daily, filling gaps in the weather record. A short training and an inexpensive gauge are all you need to join this nationwide network. Your readings are used by meteorologists, farmers, and researchers every day.

“Loved this one — the organizer had everything set up before we arrived and explained exactly what we'd be doing. It ran about 30 minutes long, which caught a few of us off guard, so plan for that. Would definitely come back.”
💡 Bring closed-toe shoes and a water bottle — it gets warm.
