Atmospheric PM1 has an impact on health and the environment, and is highly variable. PM1 filter samples were collected in urban roof and street sites in two Mediterranean cities in Europe (Barcelona and Madrid) to study the spatial and temporal trends of primary and secondary organic tracer compounds. Both cities are exposed to modern urban emission sources with intensive traffic in their centers...
Broadband UV-B irradiance measurements (YES UVB-1) from a 4-year campaign in Córdoba City (31° 24′ S, 64° 11′ W, 454m a.s.l.) and the TUV 4.1 model were used to apply a new approach (exp-mod) to convert broadband irradiance measurements at surface under clear sky conditions to actinic flux and then to J-values. The structure of the model was used to split each measurement into its diffuse and direct...
