1. PROJECT ------------ Title: Multiple equilibria of climate: outputs Funding organisation: NSF, NOAA 2. DATASET ------------ Description: Outputs from the MIT General Circulation Model (MITgcm) run in the idealized "Boomerang" configuration (two 45 degree-wide land masses defining a narrow Atlantic-like basin and a wide Pacific-like basin connecting to an unblocked Southern ocean). This dataset contains all data necessary to reproduce figures and analysis published in Ferreira et al. (2018, doi:10.1029/2018GL077019). It includes outputs from the ocean, atmosphere, sea ice, carbon cycle, and land surface components of the MITgcm simulations of the Cold and Warm states. Outputs cover the last 50 years of both simulations after spin-up. Outputs are yearly averages.

CONTENTS ------------ File listing README.txt : this file GridAtm, GridOcn: grid files of the atmosphere and ocean components Warm_State, Cold_State: directories with outputs from the Warm and Cold state simulations These directories contains subdirectories with outputs for the atmosphere (Atm), ocean (Ocn), sea ice (Ice), carbon cycle (PTr) and land (Lnd). The directory MON contains timeseries (monthly snapshots) of key variables (e.g. global mean temperature). Data are provided in netcdf format (see section 5 for tools to read the data). Description of the variables are given in the "available_diagnostics.log" files. The Atm and Ocn directories contain the STDOUT.* files which summarizes all parameters used in the simulations. available_diagnostics.log_ocn, available_diagnostics.log_atm: descriptions of outputs of the MITgcm (including units, location on grid, 2d/3d). Names match those found in the netcdf files. 5. METHOD and PROCESSING -------------------------- All outputs were generated with the MITgcm (http://mitgcm.org/, https://github.com/MITgcm/MITgcm). Versions are indicated in the STDOUT.* files. Outputs are provided in netcdf format and can be read with a variety of software. Subroutines for Matlab and Python to read the MITgcm outputs are available on the MITgcm github repository (https://github.com/MITgcm/MITgcm/tree/master/utils).
