Model COLA 2: Elaborations


Participation

Model COLA2 is an entry in the CMIP1 intercomparison only.


Spinup/Initialization

The procedure for spinup/initialization of the COLA coupled model was a follows (reference: E. Schneider, personal communication):

Land Surface Processes

Sea Ice

Chief Differences from the Closest AMIP Model

In addition to differences in horizontal resolution, the atmospheric component of the COLA 2 model differs from AMIP model COLA COLA1.1 (R40 L18) 1993 in the following respects:
