Abstract:
The GFDL R30 climate model is a coupled atmosphere-ocean
general circulation model (AOGCM). Its four major components
are an atmospheric spectral GCM, and ocean GCM, and
relatively simple models of sea ice and land surface processes.
The name "R30" is derived from the resolution of the
atmospheric spectral model (rhomboidal truncation at wave
number 30).
... This R30 model is identified as GFDL_R30_c in the Third
Assessment Report of the Intergovernmental Panel on Climate
Change (IPCC). See Chapter 9, Table 9.1 of "Climate Change
2001: The Scientific Basis" IPCC Working Group I (2001).
The model output stored on this server is taken from six
experiments conducted at GFDL using the GFDL_R30_c model.
Data files produced by one long-running control integration
(one with no changes in external forcings, e.g., constant CO2)
and five climate change scenario experiments have been made
accessible to interested researchers. More information regarding
the individual experiments is found in the Control & Transient
Forcing Experiments section of these web pages.
The Experiments are identified as follows:
The Control Experiment ctl_06
The Climate Change Scenario Experiments IPCC_A2_01 and IPCC_B2_01
The Climate Change Scenario Experiments: gps_01, gps_02, and gps_0
This numerical model was developed and the experiments
conducted by members of the Climate Dynamics & Prediction
Group at the Geophysical Fluid Dynamics Laboratory (GFDL)
located in Princeton, New Jersey. GFDL is part of the National
Oceanic and Atmospheric Administration's (NOAA's) Oceanic
and Atmospheric Research (OAR).
