We evaluate a set of ultraviolet solar radiation (UVR) measurements collected in six locations in Peru: Ica, Tacna, Moquegua, Arequipa, Cajamarca and Marcapomacocha, whose altitudes vary from sea level to 4479 m. The analysis involved the validation and analysis of the ultraviolet index (UVI) and the daily erythemal doses (D-Er). Clear-sky filtered data were compared with numerical simulations provided by the Tropospheric Ultraviolet and Visible (TUV) radiation model in order to estimate numerical regression equations. These equations showed high determination coefficients (R 2 > 0.91) statistical significance (p < 0.0001). Results show that the maximum UVI observed in Peru was 23.5 in Marcapomacocha (4479 m above sea level). Regarding D-Er, the highest means were observed in summer at the city of Arequipa with daily averages closer than 7.9 kJm -2 (± 1.3 kJm -2 ). However, the highest ...

The changing composition of the atmosphere, driven by anthropogenic emissions, is the cause of anthropogenic climate change as well as deteriorating air quality. Emission inventories are essential to understand the contribution of various human activities, model and predict the changing atmospheric composition, and design cost-effective mitigation measures. At present, national emission inventories in South America (SA) focus on Greenhouse Gases (GHG) as part of their obligation to the United Nations Framework Convention for Climate Change (UNFCC) within the framework of their national communications. Emission inventories other than GHG in SA focus mainly on growing urban areas and megacities. Therefore, studies examining air quality at national, regional or continental scales in SA depend on (down-scaled) global emission inventories. This paper examines the emission estimates of air pol...
