Abstract

An operational method has been developed to forecast the maximum hourly concentration of NO% in Florence urban area during the current day. The situations that can lead to high concentrations of NC>2 have been identified and described by means of a statistical analysis of the environmental conditions measured. The forecasting method has been developed through the following tasks: • preliminary study to select the most significant environmental parameters and synoptic conditions; • characterisation of each day using the data measured till 10 am; • selection of the best algorithm to compare the current day with the past events and to individuate
