Ozone is actually one of the most important atmospheric pollutants in industrial countries. Measurement is well achieved by continuous monitors but a better information on ozone levels would be given by a denser monitoring network, made possible by using a lighter and cheaper technique like microsensors.Such sensors have been tested successfully in the laboratory. We have therefore undertaken a large on-site campaign, on air quality monitoring stations of the French Networks, to validate the use of microsensors on-site. First results of the campaign were improvements in conditioning and calibration procedures. Then, stabilised sensors showed most ozone values within an interval of +/- 30 % of the concentrations given by the monitors.
