5. Air Resource Management PB-Piedmont Model Fine scale time-dependent model for predicting the nocturnal movement of smoke from prescribed burns over rolling terrain typical of that of the Midwest and the SouthFine scale time-dependent model for predicting the nocturnal movement of smoke from prescribed burns over rolling terrain typical of that of the Midwest and the South Purpose:Purpose: –Pre-burn decision-making: If I burn tomorrow, will I smoke up a road tomorrow night? –Post-burn decision-making: Now that I have burned today, where is the smoke most likely going tonight?
