UM-UKCA interactive stratospheric aerosol model time-integrated data for perturbed parameter ensemble of volcanic eruptions

This dataset contains summary 3-year time-integrated data of the global mean volcanic stratospheric aerosol optical depth, effective radiative forcing and anomalous deposited sulfate on Antarctica and Greenland. The data are from 82 model simulations of volcanic eruptions that have different sulfur dioxide emissions, eruption latitudes and emission altitudes. Two ensembles were conducted for eruptions starting in January and July. Each simulation was run for ~3 years in a year 2000 timeslice condition. The simulations are from the Unified Model coupled with the United Kingdom Chemistry and Aerosol Scheme (UM-UKCA) and were conducted at a global resolution of 1.875 ° x 1.25°. This data were collected as part of the NERC Reconciling Volcanic Forcing and Climate Records throughout the Last Millennium (Vol-Clim) project. V3 is the latest data file to use.
