question 67

Multiple Choice

General circulation models (GCMs) of the atmosphere

• B)are based on statistical three-dimensional grids that characterize portions of the atmosphere and ocean in terms of climate-related variables.
• C)are pre-computer based models that estimated atmospheric and oceanic circulation and are now being used to study climate change.
• D)calculate the concentrations of greenhouse gases in the atmosphere based on data from weather stations located around the globe.
