Atmosphere Model (CAM)
The atmospheric component of CCSM is the Community Atmosphere Model (CAM). While being the atmospheric model used in the Community Climate System Model, it can also be run as a standalone atmosphere model. The most current version is 3.1, 3.0 being the fifth generation of NCAR atmospheric GCM. On May 17, 2002, its name was changed from the NCAR Community climate Model to reflect the role of the atmosphere model in the new fully coupled climate system. It shares the same horizontal grid as the land model of CCSM: a 256x128 regular longitude/latitude global horizontal grid (giving a 1.4 degree resolution). It has 26 levels in the vertical.

Famous quotes containing the words atmosphere and/or model:
“The base of all artistic genius is the power of conceiving humanity in a new, striking, rejoicing way, of putting a happy world of its own creation in place of the meaner world of common days, of generating around itself an atmosphere with a novel power of refraction, selecting, transforming, recombining the images it transmits, according to the choice of the imaginative intellect. In exercising this power, painting and poetry have a choice of subject almost unlimited.”
—Walter Pater (1839–1894)
“The playing adult steps sideward into another reality; the playing child advances forward to new stages of mastery....Child’s play is the infantile form of the human ability to deal with experience by creating model situations and to master reality by experiment and planning.”
—Erik H. Erikson (20th century)
