title: Idealized precession GCM simulations with EC-Earth-2-2

description: This repository contains output from the EC-Earth-2-2 extreme precession simulations (Prec-min / Pmin and Prec-max / Pmax). The experiment details are described in the papers given as references. In this repository, monthly output of the last 50 years of simulation is given for precipitation (in m/s), zonal wind (east-west, in m/s, parameter 165), meridional wind (north-south, in m/s, parameter 166), mixed layer depth (MLD, in m, based on a σ0 difference of 0.01 with the surface), sea surface salinity (in PSU) and thermocline depth (TCD, in m). Furthermore, climatological mean monthly output (averaged over the last 50 years of simulation) is given for surface air temperature (parameter 167), surface sensible heat flux (146), surface latent heat flux (147), surface solar radiation downwards (169), surface thermal radiation downward (175), net surface solar radiation (176), net surface thermal radiation (177), net top solar radiation (at top of atmosphere, 178), and net top thermal radiation (at top of atmosphere, 179). Furthermore the following 3D variables are given on pressure levels: geopotential height (129), specific humidity q (133), zonal wind (east-west, 131), meridional wind (north-south, 132), vertical velocity (135).
