volc-long-eq

This experiment is designed to realistically reproduce the radiative forcing resulting from the 1815 eruption of Mt.
Tambora, Indonesia. The experiment does not account for the actual climate conditions when the real event occurred
(e.g., presence and strength of additional forcing factors). Instead, the experiment is designed to span very different
initial climate states to systematically assess uncertainties in the post-eruption behavior that are related to background
climate conditions.

Length of integration
at least 20 years (mandatory), but preferably longer (30-40 years) to cover the multi-decadal oceanic response

Initial conditions
predefined states describing different states of dominant modes of variability (see "ensemble size") sampled from an
unperturbed control integration, under common constant boundary forcing across the different models (piControl
simulations from DECK).

Ensemble size
Nine simulations allow spanning warm/cold/neutral and strong/weak/neutral states of El Nino-Southern Oscillation
(ENSO) and of the Atlantic Meridional Overturning Circulation (AMOC), respectively

Forcing input data
VolMIP proposes for the volc-long and volc-cluster experiments forcing data sets constructed with the Easy Volcanic Aerosol
(EVA) module (Toohey et al., Geosci. Model Dev. Discuss., doi:10.5194/gmd-2016-83, in review, 2016). Details about EVA can
be found here.
