Got Rainfall? Join CoCoRaHS!
- A Volunteer network of daily precipitation observers.
- Simple requirements:- Watch a short training video online.- Plastic Rain Gauge ($20-25).- Internet Connection.
- Make daily precipitation reports.
- Rainfall varies greatly over short distances.
- Especially in the Desert Southwest!
- CoCoRaHS helps “fill the gaps!”
- Daily precip data is entered in a simple web form at a standard time.
- Rainfall, Snowfall, Snow Depth.
- Reports between 6:00 and 10:00 am are preferred, but not mandatory.
- Delayed reports OK.
CoCoRaHS is Volunteer-Friendly!What if I’m not home?
- Have a friend check your gauge for you.- Or, report a “Multi-Day Accumulation.”- Or, just report “Missing.”
A dense network makes a handful of “missing” observations more acceptable.
Multi-Day Precip Form
CoCoRaHS is Volunteer-Friendly!What about when it doesn’t rain for 4 months?
- “Daily Zeroes” can be sent en-masse every few days.- Just click on the days with “0.0 Precip” and hit Submit.
What is the Data Good For?- Filling gaps between the “official” rain gauges...
