Designing and evaluating regional climate simulations for high latitude land use land cover change studies
High latitude regions are undergoing substantial land use and land cover change (LULCC) arising partly from a changing climate (e.g. greening of the Arctic) and climate mitigation policies (e.g. afforestation). Despite these ongoing changes, the impacts of LULCC in high latitudes are poorly understo...

High latitude regions are undergoing substantial land use and land cover change (LULCC) arising partly from a changing climate (e.g. greening of the Arctic) and climate mitigation policies (e.g. afforestation). Despite these ongoing changes, the impacts of LULCC in high latitudes are poorly understood.

As such it is important to understand the limitations of RCMs and identify best practices for designing regional climate modelling experiments for LULCC studies at high latitudes. In this study, twelve 10-year simulations are performed over the Scandinavian Peninsula; six at convection permitting scales (dx ∼ 3 km) and six at non-convection permitting scales (dx ∼ 15 km).
