CCM1 Model Experiments
You may download monthly and seasonal data from these
experiments by choosing from the experiment name columns. Not all
data is available. The numbers on the end of the file names denote
the years. Also, NCAR/CCR diagnostic packages are available for some
experiments. You may obtain more information on these boundary conditions:
carbon dioxide volume, orbital
parameters, and paleocalendar
dates.
