*Notes: The first column is the 4-letter abbreviation code used in naming datafiles. The MM5 model was initially tested with two sets of parameters, one from PNNL and one from ISU. The MM5 model is being run by the ISU modeling group, and the results are therefore referred to as MM5I, but it is being run using the PNNL parameters because they produced better results. If data generated using the ISU parameters becomes available, it will be designated MAIP (MM5 - Alternate ISU Parameters) to try and minimize confusion.

*Note: NCEP is not a GCM, but a reanalysis, a restrospective model of the atmosphere based on observed data. NARCCAP uses NCEP-DOE Reanalysis 2, sometimes referred to as "NCEP-2".

2: Second pairing to be run

Timeslice Experiments:
The two timeslice experiments are run using the GFDL AM2.1 and the NCAR CAM3 models. These correspond to the GFDL and CCSM drivers, respectively. Each RCM is therefore paired with one of the GCMs that has a corresponding timeslice experiment.
