THE CLIMATE MODELING and Diagnostics Group at the Lamont-Doherty Earth Observatory (LDEO) of the Earth Institute at Columbia University includes more than 200 researchers studying the origin, evolution, and future of the natural world. The Climate Modeling Group carries out research in climate modeling and climate change, also taking into account important issues in the phenomenon of global warming, such as El Nino/Southern Oscillation. Climate Group builds on the data produced from general circulation models (GCMs) to answer fundamental science questions.

LDEO is developing several climate models. The Lamont Ocean-AML GCM (LOAM) is a recent recreation of the Gent-Cane Primitive Equation Ocean Model with many supplementary elements. It was developed for modeling the equatorial Pacific on a stretched longitude/latitude A-grid. Most of the horizontal features have ...
