Training AG "A" and "C" Schools are currently located in Biloxi, Mississippi, on Keesler Air Force Base. AG "A" School concentrates on weather observing and lasts approximately 3 months. AG "C" concentrates on weather forecasting and lasts approximately 9 months. Upon graduating from "A" school, AGs work toward qualification as environmental observers through completion of personnel qualification standards and job qualification requirements.
