Using a large-ensemble climate simulation dataset d4PDF, the role of temperature advection in the Arctic lower troposphere under changing level of global warming is investigated. We have taken the 30-year climatology of the non-warming simulation (HPB-NAT) as a reference and examined the difference in temperature advection under changing basic states of the historical experiment (HPB) and 2K and 4K warming experiments (HFB-2K and HFB-4K). Decomposition is made into terms related to dynamical changes, thermodynamical changes and the eddy term which is a covariance term related to the effect of sub-monthly transient eddies. This dataset is a supplimental material to the article.
