To assess the best measures for improvement of air quality, it is crucial to investigate in situ and columnar pollution levels. In this study, ground-based measurements nitrogen dioxide (NO2) ozone (O3) collected Rome (Italy) between 2017 2022 are analyzed. Pandora sun-spectrometers provided time series NO2 vertical column density (VC-NO2), tropospheric (TC-NO2), near-surface concentration (SC-NO2), O3 (VC-O3). concentrations by an urban background quality station. The results show a clear...
Abstract. To retrieve columnar intensive aerosol properties from sun–sky photometers, both irradiance and radiance calibration factors are needed. For the solar constant, V0, which denotes instrument counts for a direct normal flux extrapolated to top of atmosphere, must be determined. The solid view angle, SVA, is measure field instrument, it important obtaining sky diffuse measurements. Each three sun-photometer networks considered in present study (SKYNET, AERONET, WMO GAW) adopts...
