If you're interested in participating in a very useful meteorological observing program that's open to anyone, you might like to check out this article, which is an update to a couple of earlier blog entries we've posted since the program got started here in our state.
We've been asked to refresh the call for volunteers, so here's a recent version of a program description from the organizers – what it is, why it's needed and useful, and how you can get started if you'd like to play a part...
CoCoRaHS came about as a result of a devastating flash flood that hit Fort Collins, Colorado, in July 1997. A local severe thunderstorm dumped over a foot of rain in several hours while other portions of the city had only modest rainfall. The ensuing flood caught many by surprise and caused $200 million in damages.
CoCoRaHS was born in 1998 with the intent of doing a better job of mapping and reporting intense storms. As more volunteers participated, rain, hail, and snow maps were produced for every storm showing fascinating local patterns that were of great interest to scientists and the public. Recently, drought reporting has also become an important observation within the CoCoRaHS program across the nation. In fact, drought observations from CoCoRaHS are now being included in the National Integrated Drought Information System.
North Carolina became the twenty-first state to establish the CoCoRaHS program in 2007, and by 2010, the CoCoRaHS network had reached all 50 states with nearly ten thousand observations being reported each day. Through CoCoRaHS, thousands of volunteers, young and old, document the size, intensity, duration and patterns of rain, hail, and snow by taking simple measurements in their own backyards.
“North Carolina has one of the most complex climates in the U.S.,” said Dr. Ryan Boyles, state climatologist and director of the State Climate Office, based at North Carolina State University. “Data gathered from CoCoRaHS volunteers are very important in better understanding local weather and climate patterns.”
“An additional benefit of the program to the National Weather Service is the ability to receive timely reports of significant weather (hail, intense rainfall, localized flooding) from CoCoRaHS observers that can assist forecasters in issuing and verifying warnings for severe thunderstorms,” says David Glenn, CoCoRaHS State Co-coordinator and meteorologist with the National Weather Service in Newport/Morehead City.
How does one become a CoCoRaHS observer? Go to the CoCoRaHS website above and click on the “Join CoCoRaHS” emblem on the upper right side of the main website. After registering, take the simple online training, order your 4 inch rain gauge and start reporting!
“We are in need of new observers across the entire state. We would like to emphasize rural locations, areas of higher terrain, and areas near the coast,” added Glenn.
