This dataset contains the data used for the following paper: "Climate state dependence of precipitation variability". The following variables are available on a monthly timescale: total precipitation (TP), convective precipitation (CP), large scale precipitation (LSP), evaporation (E), poleward moisture transport (MFatmos), two-metre temperature (T2M), surface temperature (SSTK), sea level pressure (MSL) and geostrophic wind (uwind and vwind). All variables are available for five quasi equilibrium simulations of 400 years length forced with a broad range of CO2 simulations (025xco2, 05xco2, control, 2xco2, 4xco2) from 50N-90N.
