NASA GISS: Research in Climate Modeling
GISS Research Global Climate Modeling. The climate modeling program at GISS is primarily aimed at the development of three-dimensional general circulation models (GCMs) and coupled atmosphere-ocean models for simulating Earth’s climate system, although some research efforts may include the use and development of two-dimensional energy balance models (EBMs), and one-dimensional radiative-convective models (RCMs). Primary emphasis in the use of the GCMs is placed on investigation of climate sensitivity, including the climate system’s response to such forcings as solar variability, anthropogenic and natural emissions of greenhouse gases and aerosols, etc. A major focus of GISS GCM simulations is to study the potential for humans to impact the climate as well as the impact of a changing climate on society and the environment. GCM developmental research focuses on sensitivity to parameterizations of clouds and moist convection, ground hydrology, and ocean-atmosphere-ice interactions, as well as investigations of more accurate numerical methods. The program also involves development of techniques to infer global cloud properties from satellite radiance measurements of the International Satellite Cloud Climatology Project. Ongoing field and laboratory programs in palynology, paleoclimate reconstruction, and other geophysical sciences provide fundamental climate data for evaluating and validating model predictions.
