Data Communal Estimations 2023

In this archive are collected the aggregated municipal values calculated from the results of the simulations on a regional scale performed with a chemical-physical model of air quality. These are therefore not measures, but estimates that also use data from the ARPA air quality detection network. The data accessible from here are to be considered provisional until the completion of the validation process of the measures, the consequent recalculation of the values and the publication of the consolidated data; consolidated estimates for the previous year are usually available from 30 June of the current year. The pollutants and their downloadable aggregations are: • daily average weighed on the municipal territory of fine particulate matter and nitrogen dioxide (PM10, PM2.5, NO2 with associated parameter average per day). For municipalities belonging to zone D of the new regional zoning (valley grounds) is also available the estimate of the average weighted on the only urbanised part of the municipal territory (PM10 Urbanised, PM2.5 Urbanised, NO2 Urbanised with associated parameter Media Giorn.). The archive can be consulted from 01/01/2011 for PM10 and nitrogen dioxide, while for PM2.5 particulate matter it can be consulted from 01/01/2016; • maximum daily nitrogen dioxide in the municipal territory (NO2 with maximum daily parameter). The archive can be consulted from 01/01/2011; • daily tropospheric ozone maximum on the municipal territory (O3 with associated parameter Massimo Giorn.). The archive is available from 01/05/2011 and for the years 2011 to 2015 can be consulted between 1 May and 30 September; from 01/01/2016 the data is available throughout the year; • daily maximum of the eight-hour moving average of tropospheric ozone in the municipal territory (O3_MM8 with associated parameter MaxMm8h). The archive can be consulted from 01/01/2016. It should be noted that the method for calculating maximum values in the municipal territory (for nitrogen dioxide and tropospheric ozone) has been updated from 01/01/2016, the date from which the maximum value is calculated as the maximum hourly maximum weighed on the municipal territory.
