Different models of instruments have been operated: Eppley PSP and Kipp&Zonen CMP21 pyranometers for SW irradiance, and Eppley PIR and Kipp&Zonen CGR4 pyrgeometers for LW irradiance. See https://www.thuleatmos-it.it/instruments/radiometers for additional details. Radiometers are ventilated to prevent ice/dew formation on their domes. Data are recorded and uploaded with a 30-second time step. Corrections are applied to SW measurements in order to remove the thermal offset and to take into account the cosine response of each pyranometer. SW and LW irradiance measurements from Kipp&Zonen models are obtained accounting for the dependance of the radiometers’ sensitivity on temperature. Regular calibrations allow our team to monitor changes of the sensitivity with time. Quality checks are perfomed based on tests recommended for sensors enrolled in the Baseline Surface Radiation Network (BSRN). https://data.ingv.it/dataset/1217 ITA 2026-01-01T00:00:00 2906 https://data.ingv.it/person/2906 2902 https://data.ingv.it/person/2902 965 https://data.ingv.it/person/965
