| Zusammenfassung |
| Two hundred years ago a very cold and wet summer devastated agriculture in Europe and North America, causing widespread food shortages, unrest and suffering. This is usually blamed on a very large volcanic eruption - mount Tambora, in Indonesia - the previous April, but making a link between these two events has proved difficult, as the major impacts were at smaller space and time-scales than we can reconstruct with tree-ring observations and GCM simulations. To mark the bicentenary of the eruption, we have rescued weather observations from the period from about 50 sites, mostly in Europe; used the pressure observations to constrain a dynamical reanalysis, and the temperature observations to validate it. Running the reanalysis with and without volcanic aerosol forcing lets us estimate what parts of the event can be attributed to the volcano. |
