The source of the data for these products
comes from the U.S. Cooperative
Network, augmented by observations from the relatively small number of
NWS sites. These cooperative sites are operated by volunteer observers using
approved instruments and observing techniques. It is only through their efforts
that we have enough data to generate these products.
