WebOct 2, 2024 · The capabilities of the GISS GCM were assessed for its ability to simulate observed winter and summer seasons for the period 1951 to 1998. Five runs each of the models (numbered B299, B300, and B301) were used, with each set differing by the addition of known climate forcings. WebResearch at the Goddard Institute for Space Studies emphasizes a broad study of Global Change, the natural and anthropogenic changes in our environment that affect the habitability of our planet.
