Welcome



GFDL AM2.1 AGCM

    Idealized SST experiments

    The idealized SST experiments using the GFDL AM2.1 are performed by the Geophysical Fluid Dynamics Laboratory (GFDL).

    The idealized runs are 60 years long, and data of the last 50 years are saved.

    The data are available at ftp://gmaoftp.gsfc.nasa.gov/pub/data/clivar_drought_wg/GFDL/.

    List of idealized runs with the GFDL AM2.1:
