THE MONTREAL-96 EXPERIMENT ON REGIONAL MIXING AND OZONE (MERMOZ) - ANOVERVIEW AND SOME PRELIMINARY-RESULTS

The MERMOZ (Montreal-96 Experiment on Regional Mixing and Ozone) field experiment was conducted in the greater Montreal area in June 1996. T he measurement program was designed to examine several aspects of boun dary layer dynamics and chemical transport. The project featured high- resolution real-time simulations with a mesoscale meteorological model driving several air quality models; the deployment of a research airc raft, fully instrumented for turbulent flux measurements; and a number of other supporting meteorological measurements such as two boundary layer wind profilers, a Doppler weather radar, and a special network o f surface stations, upper-air soundings, tethersondes, and ozonesondes . An overview of the MERMOZ field program is presented with some preli minary results on various aspects of the experiment.
