Smoke Impacts During the Control of Crippin Fire
Summary and Conclusions
Quantification of impacts during events is difficult
Complaints and monitoring do not always agree
Decision to allow other burning relies on impact analyses using the corroboration of monitoring, modeling, meteorology and social factors
Discussion
