Total Incident Solar Radiation (TISR) and Total Reflected Solar Radiation (TRSR) data, acquired from May 2018 to December 2020 in the Bessanese high-elevation experimental site (Western Italian Alps, 2659 m a.s.l.), are presented. TISR and TRSR data have been acquired by using a Kipp & Zonen, CMA 6 model, albedometer. For data validation, we adopted QC recommended by WMO, which is described in detail in the Guide to Climatological Practices (WMO 2018). Activity carried out as part of the collaboration between CNR-IRPI and ARPA Piemonte. This work was carried out in the framework of RIST2 project, co-financed by the Fondazione Cassa di Risparmio di Torino.
