Run for 80 years. Simulations should be branched from an 1850 control simulation (piControl) at least 80 years prior to the end of the piControl simulation so that deforest-globe and piControl can be directly compared. All pre-industrial forcings including CO2 concentration and land-use maps and land management should be maintained as in the piControl. Deforestation should be restricted to the top 30% of land grid cells in terms of their area of tree cover. Effectively this concentrates deforestation in the tropical rainforest and boreal forest regions." ;
