INTRODUCTION TO CCM3
------------ -- ----

The NCAR Community Climate Model (CCM3) is a stable, efficient, documented,
state of the art, atmospheric general circulation model designed for climate
research on high-speed supercomputers and select upper-end workstations.

CCM3 is a free resource for scientists and graduate students in a wide array 
of specialties to use for conducting global modeling experiments in their
particular area of expertise without spending decades of their careers
developing a global climate model.

Over the last 10 years, CCM0, CCM1 and CCM2 have been used by a wide variety of
scientific institutions around the world for basic research into such areas
as nuclear winter, climate predictability, atmospheric chemistry,
paleoclimate, biosphere-atmosphere transfer, CO2 warming, climate prediction
and climate change.
