Pollutant concentration and stratification in urban heat island

Diurnal variation of oxidants and COH monitored in the Calgary urban heat island correlated with changes in atmospheric stability and surface activity. Profiles of COH showed that an elevated plume existed in the city in 60% of the summer-fall transition period. Cold air drainage contributed substantially to the high frequency. Observed discontinuity in COH-temperature relationship is partially explained by chinook effects and ice crystallization.
