Two models are under development, PB-Piedmont and PB-Coastal Plain. PB-Piedmont is designed to simulate smoke movement over complex inter-locking ridges and valleys with ridge to valley elevation differences less than 50 meters, which represents elevations typical of the Piedmont and upper coastal plain of the southern and eastern United States. PB-Coastal Plain is designed to simulate smoke movement over forest land within 20 miles (32 km) of coastlines where land/water circulations can significantly impact smoke movement. The prototype models are updated hourly with surface weather when it becomes available. Users can upload the data from the Internet. Both models include software for data decoding and extraction of data needed to run the models. Thus in current form, PB-Piedmont and PB-Coastal Plain are "nowcast" models. In 2001, the Forest Service, as part of the National Fire Plan, set up five regional modeling consortia to provide for its customers products derived with high-resolution weather data. The Southern High-Resolution Modeling Consortium, located on the University of Georgia Campus, will make 48-hour predictions possible using PB-Piedmont and PB-Coastal Plain.
