Simulated summertime (June-August) average temperature changes in 536 CE due to the stratospheric aerosol cloud resulting from an unknown volcanic eruption reconstructed here based on contemporary written records and ice core sulfate measurements. The simulated temperature changes, ranging from 1-3 ° C over Europe, show good agreement with estimates from two tree-ring temperature  reconstructions based on trees in Northern Scandinavia.
