FOAM is a fully coupled, mixed-resolution, general circulation model designed for high-throughput (simulated years per day) while still providing a good simulated mean climate and simulated variability.
FOAM uses the combination of a low resolution (R15) atmosphere model, a highly efficient medium-resolution ocean model, and distributed memory parallel processing to achieve high throughput on relatively modest numbers of processors (16-64). The quality of the simulated climate compares well with higher resolution models. No flux corrections are used.
FOAM's intended purpose is to study long-term natural variability in the climate system. FOAM is also well suited for paleoclimate applications.
FOAM is highly portable and runs on a wide range of parallel computers.
