UM-UKCA model data for study investigating the QBO response to large tropical eruptions
Abstract
This dataset contains summary 36-month data of the global mean volcanic stratospheric aerosol optical depth, temperature, sulfate aerosol mass concentration and wind velocities necessary for analysing the quasi-biennial oscillation (QBO). The data are from 8 model simulations of volcanic eruptions that have different sulfur dioxide emissions, eruption initiation date/season and QBO phase at the time of eruption. Three control ensembles were conducted for each initial condition. The simulations are from the Unified Model coupled with the United Kingdom Chemistry and Aerosol Scheme (UM-UKCA) Vn.11.2 and were conducted at a global resolution of 1.875 ° x 1.25°.
Variables for calculating the QBO momentum budget (w*, flux divergence) are contained in the files ending ‘_momentum.nc’.
There are files for each initial condition named '{SEASON}_{SO2_INJECTION_MAGNITUDE}_{QBO_PHASE}.nc'.
There are 12 control files to give three ensemble members for each initial condition. These files are named ‘{SEASON}_{QBO_PHASE}_control_{no.}.nc’ for example: ‘July_wQBO_control_2.nc’.
