Data sets

A global database of land surface parameters at 1 km resolution in meteorological and climate models (https://opensource.umr-cnrm.fr/projects/ecoclimap/files) V. Masson, J. L. Champeaux, F. Chauvin, C. Meriguet, and R. Lacaze https://journals.ametsoc.org/doi/pdf/10.1175/1520-0442%282003%2916%3C1261%3AAGDOLS%3E2.0.CO%3B2

Short summary

Temperature and precipitation can have abnormal states due to climate change and exert a significant impact on the regional hydrologic cycle. We assess the hydrologic component changes in the Alps and northern Italy, on the basis of regional future climate (FC) conditions, using the UTOPIA land surface model. The annual mean number of dry (wet) days increase remarkably (slightly) in FCs, thus increasing the risk of severe droughts and slightly increasing the risk of floods coincidently.
