Climate data at very-high resolution (1 km spatial resolution) for Sierra Nevada, the highest mountain region in the Iberian Peninsula located in southeastern Andalusia (Spain). Data obtained using the Weather Research & Forecasting (WRF) model v4.3.3 (Skamarock et al., 2021) driven by the ERA5 reanalysis (Hersbach et al., 2018). The PBL was fixed to the Asymmetric Convective Model version 2 (ACM2, Pleim, 2007). Both, long- and short-wave radiation were parametrized using the Community Atmosphere Model 3.0 (CAM3.0, Collins et al., 2004). The microphysics scheme was the WRF single-moment 7-class (WSM7, Bae et al., 2019), and the land surface model the NOAH MP (Niu et al., 2011). The convection scheme was deactivated.
