title>NCAR TN-391: CCM2 Datasets and Circulation Statistics
I. Introduction
The algorithms defining the NCAR Community Climate Model, Version 2 (CCM2)
were frozen in October 1991. During the succeeding year, the code underwent
further development to increase its efficiency and clarity. All components
were thoroughly documented in the process. The model code was frozen and
released for general use in October 1992. The history tapes from the
primary control runs were also made available for community use then.
Since that time a significant number of additional simulations have
been made with the basic model. These include simulations at different
resolutions than the one at which the model was developed and simulations
with different specified sea surface temperatures. In addition, a simulation
with the optional BATS land surface model has been carried out. While these experiments
were run, various condensations of the original history tapes were
also made, and various circulation statistics were calculated and saved.
These simulations and condensations represent a large investment of
computing resources and provide a valuable data base for further
analysis by the diverse group of CCM researchers interested in a wide
variety of problems. All these simulations are now available for
open, general use. This technical report documents the data from
these simulations and condensations.
The algorithms defining CCM2 are detailed in Hack et al. (1993). That
technical note also provides a complete list of references to papers
that provide the developmental background for many of the components
in CCM2. The User's Guide by Bath et al. (1992), provides technical
details of the model and history files. The code itself is documented
with inline comments.
