The town of Smog, Idaho is located in a river valley and has a footprint of 6 km x 2 km. It has an average daily emission rate of 1000 kg/day of PM2.5 into the atmosphere from wood burning stoves. The background concentration of PM2.5 is 0.5 µg/m3. During a cold winter day in Smog, the mixing height is only 50-m and the average wind speed is 2 m/s entering perpendicular to 2 km dimension. Assume no depositional loss for PM2.5.
