Currently we have more than 130 observers who help us measure daily precipitation

One small measurement to make.
One giant impact that measurement makes upon the millions that depend upon water.
We encourage anyone who has an interest in the weather, a desire to learn more about weather and climate, and enthusiasm to report daily observations to Join CoCoRaHS. We pride ourselves with having trained observers, either through the online session or by attending group training.

FAQs (Frequently Asked Questions) About CoCoRaHS
How Do I Get Started?
Sign up today and enter information about your location and your contact preferences.
You will receive a welcome e-mail with your new CoCoRaHS ID and instructions.
As soon as you have a user name, password and a rain gauge, you many enter observations immediately!
How Do I Get a Rain Gauge?
We strongly encourage you to purchase a plastic 4" rain gauge. This will ensure that the data collected by CoCoRaHS observers is not only consistent throughout Massachusetts, but between Massachusetts and the rest of the country! Automated rain gauges can be prone to errors in measurement, so we prefer (but do not require) you to use the 4" plastic gauge. Unfortunately, we do not have any spare rain gauges to give away.
The rain gauge costs around $30 and may be purchased at: WeatherYourWay.com or Ambient Weather
How Do I Report My Precipitation Amounts?
Most observers report online or with the CoCoRaHS "App" which is available for iPhone and Android devices. If necessary, you can also report by phone at 970-491-6300.
Is Training Available?
Yes, we offer training online through Training Slideshows or YouTube Videos
Occasionally, we also hold in-person training sessions. We'll post the dates here as they are scheduled.
What If I Can't Report Every Day?
Not to worry. Just report as often as you can. Many of us have other commitments including work, school, and vacation time. And sometimes the weather makes it difficult to go outside and take your reading from the rain gauge! The nice thing about CoCoRaHS is there is a way to report "multi day" totals if you need to!
How Is My CoCoRaHS Data Used in Rhode Island?
CoCoRaHS reports are used in real-time and for climatological purposes. Some users include the National Weather Service (NWS), State and Local agencies, the media, and the public. For example, the NWS office in Taunton uses CoCoRaHS reports as part of rainfall and snowfall listings in Public Information Statements during storms. The NWS Northeast River Forecast Center uses daily precipitation data to supplement precipitation analyses, which are used to help predict river flows throughout the region. The data is also used for water resource management provided to the Rhode Island Water Resources Board.
Who Can I Contact for More Information or If I Have More Questions?
