Smoke models and their emissions-related uncertanties

View article.

Three models were evaluated in this study: CALPUFF, DAYSMOKE and CMAQ during different prescribed burn and wildfire episodes occurring throughout the southeastern US.  Results suggested that CALPUFF could not be determined to be a suitable model for simulating the air quality impacts of fires. Model evaluation indicated that DAYSMOKE can be turned into a reliable a short‐range smoke‐impact prediction tool for land managers. On a regional scale, PM2.5 impacts of prescribed burns and wildfires are best predicted by air quality models such as CMAQ.
