https://data.ingv.it/dataset/1218 Downward-looking radiometers have been installed on July 2016 to collect the upward component of the SW and LW irradiances. Eppley PSP pyranometer and PIR pyrgeometer are located about 100 m West of THAAO on a metal frame at about 2.3 m agl. Electronic levels monitor any possible deviation from the horizontal in the North-South and Est-West directions. See https://www.thuleatmos-it.it/instruments/radiometers for additional details. Radiometers are not ventilated. Data are recorded and uploaded with a 30-second time step. 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). 2026-08-07T00:00:00 https://data.ingv.it/person/2905 2905 10.13127/thaao/usli_hr ITA 2902 https://data.ingv.it/person/2902 01-01-2026 scienza https://data.ingv.it/person/scienza https://data.ingv.it/person/205 205 5017 https://data.ingv.it/person/5017 https://data.ingv.it/person/2903 2903 2026-01-01T00:00:00 2906 https://data.ingv.it/person/2906 https://data.ingv.it/person/2904 2904 http://www.opendefinition.org/licenses/cc-by Portale dei dati aperti Open Data Portal]]> https://data.ingv.it High Resolution Upward Shortwave and Longwave Irradiances at the Thule High Arctic Atmospheric Observatory (THAAO_USLI_HR) {"type": "MultiPoint","coordinates": [[-68.8,76.5]]} 2901 https://data.ingv.it/person/2901 08-07-2026 https://data.ingv.it/person/5118 5118 customer service Agenzia Nazionale per le nuove tecnologie, l’energia e lo sviluppo economico sostenibile (ENEA) https://data.ingv.it Agenzia Nazionale per le nuove tecnologie, l’energia e lo sviluppo economico sostenibile (ENEA) https://data.ingv.it/person/965 965 ambiente 5119 https://data.ingv.it/person/5119
