The NEW SFE PB-Piedmont fact sheet (pdf) is out! PB-Piedmont is is a web browser-based tool for modeling nighttime and early morning smoke movement in the Piedmont region of the South. PB-Piedmont is useful for predicting where smoke and fog may accumulate at night to assess the potential for impacting roadways or smoke sensitive areas. Validation tests have shown that PB-Piedmont also works in other regions with less significant topographic relief. Check out the new fact sheet and then go try out the model yourself.
