People from all walks of life are fascinated by weather and make routine measurements. The “Cooperative Network” operated by the National Weather Service (or NWS) is a network of several thousand volunteers from across the country that routinely make and report weather observations. This Coop has operated continuously since 1890. The group includes about 9,000 weather observes who systematically measure high and low temperatures, rainfall and snow accumulation every day. These observations are archived at the National Climatic Data Center and are a large part of the historical weather record of the country.
Another group, the Community Collaborative Rain, Hail and Snow networks, or CoCoRaHS, includes 15,000 volunteers who help measure and report precipitation type and amounts every day. Observations of precipitation by a large group of volunteers are critical to understanding storms as precipitation varies widely from place to place even in a single storm. Such observations are useful for assessing flooding hazards and rapid snow melting. You can join CoCoRaHS at http://www.cocorahs.org.
There are also tens of thousands of citizens that serve as NWS severe weather spotters. The NWS relies on these storm spotters, along with radars, satellites and other data to supply observations that help in NWS’ decision making process of issuing and verifying severe weather warnings. The NWS is always looking for volunteers to help get the word out about severe storms. You can find out more about this group and sign up for classes and become a trained spotter at http://www.crh.noaa.gov/mkx/?n=spotters. It is a good class to take as we approach severe weather season.
So, if you enjoy making weather observations, join one of these groups and be one of the nation's weather observers!
