Data and Python scripts for "Manifold increase in the spatial extent of heatwaves in the terrestrial Arctic"

Data and Python scripts for reproducing the figures and results included in the manuscript "Manifold increase in the spatial extent of heatwaves in the terrestrial Arctic". Figures 1-4 are produced via respective Python codes. Heatwave magnitude index daily (HWMId) for ERA5-Land is available from. hw_era5land.nc file. HWMId fields for CMIP6 models are included in cmip6_hwmid.zip. The underlying data behind the figures 1-4 are included in data_to_produce_figs.zip. The paper is published in Rantanen, M., Kämäräinen, M., Luoto, M. et al. Manifold increase in the spatial extent of heatwaves in the terrestrial Arctic.
