Background on WACCM
The Whole-Atmosphere Community Climate Model
(WACCM) is a comprehensive numerical model,
spanning the range of altitude from the Earth's surface to the thermosphere. The
development of WACCM is an inter-divisional collaboration that unifies certain aspects
of the upper atmospheric modeling of HAO, the middle atmosphere modeling of ACD, and
the tropospheric modeling of CGD, using the NCAR
Community Climate System Model (CCSM)
as a common numerical framework.
The initial version of WACCM (WACCM-1b)
incorporates physical and chemical processes
required to investigate coupling between atmospheric regions from the surface to 140 km.
Further addition of upper thermospheric physics and chemistry, much of which is
currently operating in HAO's TIME GCM, will
eventually allow the model to extend upward
to about 500 km. WACCM is built upon the
numerical framework of CGD's CCSM, and is
envisaged as a flexible model environment, whose domain and
component modules can be configured according to the specific problem under study.
