|Model Name||Model Overview||Citation and Supporting Information (SI) for documentation papers|
|GFDL-ESM4||ESM4.1 Overview||ESM4 Citation/SI|
|GFDL-CM4||CM4.0 Overview||CM4 Citation/SI|
|GFDL-AM4||AM4 Overview||AM4 Citation/SI|
These files are needed to correct some CM4/ESM4/OM4p5B datasets (uo,vo,tauuo,tauvo) on the native ocean model grid.
See the CMIP6 Errata service (issue link) for the complete list of affected datasets and instructions for fixing.
GFDL SPEAR Large Ensemble Publicly Available Output
Selected output from 30-member ensembles of climate change simulations over the period 1921-2100 are available for download here. These simulations were conducted with the 50 km version of the SPEAR climate model. The simulations used historical radiative forcing for the period 1921-2014 and SSP5-8.5 forcing for the period 2015-2100.
Ocean Data Assimilation Experiments (ODA)
North American Regional Climate Change Assessment Program (NARCCAP)
Coordinated Ocean-ice Reference Experiments (CORE)
The US National Multi-Model Ensemble (NMME) is an experimental multi-model seasonal forecasting system consisting of coupled models from US modeling centers including NOAA/NCEP, NOAA/GFDL, IRI, NCAR, NASA, and Canada's CMC.
Our Data Portal Services
Public data sets from GFDL are made available through the GFDL Data Portal. The Data Portal is designed to allow one to download files, display data files attributes, and graphically display the data. One can download complete files via "http" and "ftp" access. One can also display data file attributes that provide information about file contents without having to download the file itself. Continued development of the Live Access Server is ongoing to enhance the ability of a remote user to graphically display the data.
Our Public Data Files
Registration for the GFDL Data Files is free. Users are requested to complete the Registration Form for Public Data Files (found on the right hand menu) when they first begin using the data portal. Information from this form will be used to provide registered users with news on when additional public data becomes available and when corrections are made to existing public data. The information gathered will not be used for any purposes other than to send notices about GFDL Data Portal Services.
The data files on the data portal are stored in netCDF (network Common Data Form), and can be identified by the suffix ".nc". The files are intended to be compliant with the COARDS conventions for the standardization of netCDF files. More information about netCDF, a machine independent format for representing array-oriented scientific data, can be found at the Unidata Program Center netCDF website.
This site implements the following:
- the Distributed Oceanographic Data System (DODS) package from Unidata/ UCAR
- the Grid Analysis and Display System - DODS Server (GDS) package from COLA/ IGES
GFDL Contribution to Model Intercomparison Projects (MIPs)GFDL participates in a variety of model intercomparison projects (MIPs). You can see the primary point of contact for a MIP at this link: MIP Contact Information . We highly recommend that you use GFDL.Climate.Model.Info@noaa.gov for most inquiries.
