Recent changes and drivers of the atmospheric evaporative demand in the Canary Islands 2016 Access copy available to the general public Unrestricted We analysed recent evolution and meteorological drivers of the atmospheric evaporative demand (AED) in the Canary Islands for the period 1961-2013. We employed long and high-quality time series of meteorological variables to analyse current AED changes in this region and found that AED has increased during the investigated period. Overall, the annual ETo, which was estimated by means of the FAO-56 Penman-Monteith equation, increased significantly by 18.2 mm decade-1 on average, with a stronger trend in summer (6.7 mm decade-1). In this study we analysed the contribution of (i) the aerodynamic (related to the water vapour that a parcel of air can store) and (ii) radiative (related to the available energy to evaporate a quantity of water) components to the decadal variability and trends of ETo. More than 90 % of the observed ETo variability at the seasonal and annual scales can be associated with the variability in the aerodynamic component. The variable that recorded more significant changes in the Canary Islands was relative humidity, and among the different meteorological factors used to calculate ETo, relative humidity was the main driver of the observed ETo trends. The observed trend could have negative consequences in a number of water-depending sectors if it continues in the future. info:eu-repo/grantAgreement/ES/MINECO/CGL2014-52135-C3-1-R info:eu-repo/grantAgreement/ES/MINECO/CGL2014-517221-REDT info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 4.437 2016 WATER RESOURCES 3 / 88 = 0.034 2016 Q1 T1 GEOSCIENCES, MULTIDISCIPLINARY 12 / 188 = 0.064 2016 Q1 T1 2.361 2016 Water Science and Technology 2016 Q1 Earth and Planetary Sciences (miscellaneous) 2016 Q1 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Azorin-Molina, C.
