Comparative measurements of solar UV irradiation at the high-mountain stations of BEO-Moussala (BG) and NAO-Rozhen (BG)

Damaging UV radiation is an important object of investigation related to its impact on biological species. Data acquired at high-altitude stations reveal dangerous events of incident UV radiation reaching the Earth surface. Continuous multi-UV spectral measurements by open-source equipment could further deepen the knowledge of solar light propagation and the events of radiation transfer and atmospheric absorption processes. This report describes recent results on high-resolution UVA, UVB, UVC measurements of solar UV radiation at the mountain stations in Bulgaria.
