Initialization Method (Cf. the review by Stouffer and Dixon 1997 concerning the rationale for the following categories.)

Run Length: The length of the simulated output data that are archived for the CMIP intercomparison. Note, this run length may be shorter than what actually has been simulated, to date, by the coupled model.

Surface Air Temperature: The definition of each model's "surface air temperature" is summarized. L denotes the temperature of the lowest atmospheric level, with the associated sigma value given in parentheses.  I denotes an air temperature that is intermediate between the temperatures at the ground and at the lowest atmospheric level, with the nominal height noted in parentheses (expressed either in meters above the surface or as an intermediate sigma level).

Missing Data: Data not provided in the CMIP1 requested data list.
