This dataset contains temperature and horizontal heat convergence output from four different climate modelling simulations using a slab-ocean setup for the Norwegian Earth System Model (NorESM) used to evaluate the Arctic climate response to changes in mid-latitude SO₂ aerosol emissions.

Emissions from year 2000 are treated as the control simulation, while SO₂ emissions from Europe are increased by seven times the year 2000 values for the modified ones. The role of atmospheric and ocean energy transport is surmised from slab-ocean simulations where the atmospheric and ocean components are modified separately. Results presented here are the average of the final 50 years of the simulations.

Data description

The data are included in one netcdf file (NetCDF-3/CDM, 1.3 Mb) with temperature and horizontal heat convergence for three different simulations expressed as differences from the control (year 2000) simulations:

• control - modified atmosphere
• control - modified ocean
• control - modified ocean+atmosphere

In addition, the netcdf file also contains seasonal values for the horizontal heat convergence.
