WRF-data analysis at Svalbard 1989-2010

WRF-data analysis at Svalbard 1989-2010

A polaroptimized mesoscale climate model, Polar Weather Research and Forcasting model (WRF), has been used over the Svalbard archipelago for analysing last trends in climate. The climate model has been downscaled by the reanalysis model ERA-Interim to 8 km spatial resolution for the period 1989-2010...
