| Abstract |
Although pollutant emission patterns play important roles, they cannot adequately explain the diurnal variations in carbon monoxide concentrations found in urban areas. In this study, hourly data from a large network of carbon monoxide monitoring stations, with instrumentation corrected for moisture interference, are analyzed and compared with traffic flow and meteorological conditions at several locations in Maryland. The meteorological phenomena that appear to be important in explaining the diurnal variations involve the ventilation effects resulting from variable wind speeds and mixing heights. |
