Open fire campaign in Conflenti (Calabria, Southern Italy) - Results of multiparameter measurements performed in 2025

This dataset features the results of a campaign aimed at the multiparameter detection of potential open fire emissions. A temporary observation site was set up in the hamlet of San Mazzeo within the municipality of Conflenti (Catanzaro province, Calabria, Southern Italy) (Lat: 39.0344 N; Lon: 16.2644 E; Elev: 930 m ASL), to perform continuous measurements of particulate matter (PM1, PM2.5, PM4, PM10), nitrogen oxides (NO, NO2), formaldehyde (HCHO), and black carbon (BC) between July and August 2025. A mast measured key meteorological parameters, specifically wind speed and direction, relative humidity, temperature, and air pressure. All data are aggregated on a hourly basis. For past studies concerning the detection of open fire emissions in the area, performed at the main CNR-ISAC Lamezia Terme (LMT) observation site, refer to Malacaria et al. (2024: https://doi.org/10.3390/fire7060198) and D'Amico et al. (2025: https://doi.org/10.3390/gases5010005).
