The CMN-PV facility at S. Pietro Capofiume (50 km from Bologna) is located at the meteorological station "Giorgio Fea" which is owned by ARPAE Emilia-Romagna (43°21'N, 12°34'E, 11 m asl). The measurement site, part of the ACTRS-Italy neywork, is classified as rural background.
It is equipped with in-situ near-surface monitoring of SO2, particulate matter sampling for atmospheric chemical speciation, speciation in continuous of non-refractory chemical species (by Aerosol Mass Specrometer, AMS) and measurements of number concentration ( by twin - DMPS in collaboration with the University of Kuopio). A MAX-DOAS system (SkySpec-2D-210) is available at the station for measurement of trace gases (NO2, SO2, HCHO, HONO, Glyoxal, BrO, IO, Ozone). Further observations will be implemented during 2022: the characterization of physico-chemical-optical properties of both columnar aerosol population (sun photometry and lidar) and at ground (aerosol scattering and absorption measurements), together with an accurate evaluation the radiative balance and albedo description (solar tracker equipped with radiometers for solar and thermal down-welling radiation).
ARPAE Emilia-Romagna runs "near-surface" measurements of nitrogen oxides, ozone, ammonia, PM10 and PM2.5 as well as meteo-radar measurements, radio-soundings (at 00:00 and 12:00 UTC), PM2.5 chemical composition (offline) and operates a phenological station.
The facility is hosted in an air-conditioned shelter (15 m2) equipped with fast internet connection which allows for real-time data delivery and remote control of instrumentations. Two sampling systems (ACTRIS-compliant) designed for trace gases and aerosol particles (respectively) are available at the station. Both the sampling systems are characterized by monitoring of T and RH with active control of air fluxes. Multiple inlets to the sampling systems are available for the external users (diameters: 1/4" for trace gases and 1/4", 1/2" and 3/4" for aerosol). Three quartz windows (one on the roof, two on the walls) are available for vertical and horizontal remote sensing observations. Support structures to research activities are available at the field station: a chemistry laboratory, wi-fi covering the entire area, distribution of electric current through specific towers in different locations of the field, a 10-m two-storey tower.
