(orcid)0000-0001-8227-5689 Assessment of the variability of atmospheric pollution in national parks of mainland Spain 2016 Access copy available to the general public Unrestricted Air quality in nine National Parks in mainland Spain was assessed analysing SO2, NOx, O3, PM10 and PM2.5 data from background stations. As emissions in and around parks are limited, the levels of primary pollutants are low. Concentrations of secondary pollutants are high especially in summer due to photochemical production. The geographical variability of pollutants responds to regional emission patterns and the dominant circulation regimes in different regions resulting in west-east gradients for O3 and PM. Seasonal variability of pollutants was also interpreted in virtue of transport scenarios, changes in photochemical activity and emissions variability. NOx and SO2, maximize in winter due to higher emissions while O3 and PM do it in summer due to photochemical production, lower precipitation and, in the case of PM, the occurrence of African dust outbreaks. The diurnal evolution was interpreted in virtue of variability in emissions and changes in the Planetary Boundar Layer height. info:eu-repo/grantAgreement/ES/DGA/E15 info:eu-repo/grantAgreement/ES/DGA/E75 info:eu-repo/grantAgreement/ES/UZ/CUD2013-18 info:eu-repo/semantics/openAccess by-nc-nd http://creativecommons.org/licenses/by-nc-nd/3.0/es/ 3.629 2016 METEOROLOGY & ATMOSPHERIC SCIENCES 16 / 84 = 0.19 2016 Q1 T1 ENVIRONMENTAL SCIENCES 49 / 229 = 0.214 2016 Q1 T1 1.495 2016 Environmental Science (miscellaneous) 2016 Q1 Atmospheric Science 2016 Q1 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion Lozano, A.
