Introduction

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.

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).
