2. Suppose the following atmospheric altitude versus temperature data have been collected: Temperature (°C) Altitude (m) 20 100 18 200 16 300 15 400 16 500 17 б00 18 a) What would be the mixing depth? b) If the maximum daytime surface temperature is 22 °C, and the weather station anemometer at 10 m height shows winds averaging 4 m/s, what would be the ventilation coefficient? Assume stability class C and use the wind at the height halfway to the maximum mixing depth.
