Climatological stratospheric modeling

The Goddard Institute for Space Studies (GISS) Three dimensional Global Climate/Middle Atmosphere Model was used to investigate the effect of doubled carbon dioxide on the middle atmosphere. Carbon dioxide was doubled in both the troposphere and stratosphere, and the sea surface temperatures were increased in accordance with results from the GISS climate model. Additional experiments were run with different sea surface temperature distributions, and doubling the carbon dioxide only in the troposphere or stratosphere.
