Project: High-resolution Climate Data for a High-altitude Region in Southern Spain: Sierra Nevada - 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) https://smartecomountains.lifewatch.dev/. The use of very high resolution simulations allows a more adequate characterisation of the climate in regions with complex orography such as the Sierra Nevada, since at this resolution the convection is resolved by the model and is not parameterised. Summary: 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 ERA5 (Hersbach et al., 2018) plus a global warming signal calculated for the period 2070-2099 compared to 1985-2014 from an ensemble of 24 GCMs from CMIP6 under the SSP5-8.5 scenario. 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 used was WRF single-moment 6-class (WSM6, Hong and Lim 2006), and the land surface model the NOAH MP (Niu et al., 2011). The convection scheme was deactivated.
