There are many different networks of weather observations that are taken across the country and the world. Some of the networks are run by the National Weather Service, US Geological Survey, and other federal agencies. Now, there are also many networks run within the states by different agencies. The University of Georgia weather network that I am the Director of is one of these mesonets, but there are also state networks in Florida, Alabama, and North Carolina. Clemson University is also setting one up in South Carolina.
