A Model Chain Application to Estimate Mixing Layer Height Related to PM10 Dispersion Processes

Table 3

PM10 concentrations at the nine ARPAT air quality stations, with mean daily modelled wind speed and modelled MLH corresponding to Firenze-Peretola station. Values with bold font are those exceeding the threshold of 50 μg/m³.
