Supplement to cmip5.output1.MPI-M.MPI-ESM-LR.amip4xCO2 ( http://dx.doi.org/10.1594/WDCC/CMIP5.MXELa2 ) containing additional data published between DataCite DOI publication on April 13, 2012, and the DDC AR5 Reference snapshot of the CMIP5 data archive on March 15, 2013. 'amip4xco2' is an experiment of the CMIP5 - Coupled Model Intercomparison Project Phase 5 (https://pcmdi.llnl.gov/mips/cmip5). CMIP5 is meant to provide a framework for coordinated climate change experiments for the next five years and thus includes simulations for assessment in the AR5 as well as others that extend beyond the AR5. 6.5 amip4xco2 (6.5 4xCO2 AMIP) - Version 1: Identical to expt. 6.2b, but with AMIP SSTs prescribed as in expt. 3.3 (which is the control for this run).
