Time-slice experiments at approximately 50 km resolution
GFDL’s atmospheric model (AM2.1) was run in AMIP mode at high horizontal resolution (0.625° lon x 0.5° lat). High frequency (3-hourly) data from this model is available for two time periods: 1968 to 2000 using observed SST and sea-ice extent (from HADISST), and 2038 to 2070 using deviations in SST and sea-ice extent from the GFDL’s CM2.1 A2 scenario.
Due to the large volume of data the region publicly available covers the North American sector only. Three-dimensional fields are on the model’s vertical grid.
- 180° to 45°W longitude
- 10°N to 75°N latitude
- 24 levels, model’s original hybrid sigma-pressure coordinate
Interpolation to pressure levels
A sample Fortran 90 program is provided to interpolate 3-dimensional fields from model levels to constant pressure levels.
How to obtain the data
The data can be downloaded from GFDL’s data portal either by http or ftp:
