The Global Surface Air Temperature (GloSAT) model simulations were run on UK supercomputing platforms ARCHER2 and MONSooN using the UKESM1-1-LL UK Earth System Model described in Mulcahy, et al 2023 (https://doi.org/10.5194/gmd-16-1569-2023).

The simulations were run under the NERC funded project GloSAT. NE/S015647/2

The experiments and model set up are all described in:

Ballinger, A., Schurer, A., Hegerl, G., Dittus, A., Hawkins, E., Cornes, R., Kent, E., Marshall, L., Morice, C., Osborn, T., and Rayner, N.A. Rumbold, S.:(2025) Importance of beginning industrial-era climate simulations in the eighteenth century, Environmental Research Letters, 650, accepted.

This data set contains the variables and derived variables analysed in the paper Ballinger et al (2025)

These variables are taken from the 3 new model experiments described in this publication, which are

6 ensembles with all forcings 1750-2014, described as historical1750

4 ensembles with anthropogenic only forcing, 1750-1910, described as historicalANT1750

1 preindustrial control simulation run using 1750 constant forcing described as piControl1750

The 4 variables which have been archived here in netcdf format were those used in the publication:

tas - surface air temperature

thetao - ocean temperature

AMOC - Atlantic meridional streamflow

SurfaceTypes - vegetation types
