A full description of the ModelE version of the Goddard Institute for Space Studies (GISS) Atmospheric General Circulation Model (GCM) and results are presented for present-day climate simulations (c. 1979). This version is a complete rewrite of previous models incorporating numerous improvements in basic physics, the stratospheric circulation and forcing fields. Notable changes include the following: the model top is now above the stratopause, the number of vertical layers has increased, a new cloud microphysical scheme is used, vegetation biophysics now incorporates a sensitivity to humidity, atmospheric turbulence is calculated over the whole column, and new land snow and lake schemes are introduced. We compare the performance of the model using three configurations with different horizontal and vertical resolutions to quality controlled in-situ data, remotely sensed and reanalysis products. Overall, significant improvements over previous models are seen, particularly in upper atmosphere temperatures and winds, cloud heights, precipitation, and sea level pressure. Data-model comparisons continue however to highlight persistent problems in the marine stratocumulus regions. %C8 438
