Surface Ozone Concentrations on the Colorado Front Range

This animation shows simulated hourly surface ozone concentrations during the 2014 FRAPPÉ campaign. The simulations have been performed with the Weather Research and Forecasting (WRF) Community Multiscale Air Quality (CMAQ) model.

The simulations have been conducted with a 4 km x 4 km grid horizontal resolution and show the frequent occurrence of high ozone pollution in the Colorado Front Range and the transport of this pollution into the nearby mountains during upslope events.

The model represents well observations made on the ground and from aircraft during the 2014 FRAPPÉ campaign (https://www2.acom.ucar.edu/frappe).
