RegCM is a 3-dimensional, sigma-coordinate, primitive equation regional climate model.

Version 3 of RegCM is the latest. It is developed and supported by scientists inside and outside of PWC/ICTP

RegCM3 is freely available at http://www.ictp.trieste.it/~pubregcm/RegCM3/

The gziped RegCM3 code regcm.tar.gz; (updated on November 27, 2009) 

For Terrain&ICBC preprocessing, DATTYP could be ECMWF, EH5OM, ERA40, FVGCM, Further NEST (FNEST), NNRP1, NNRP2 and the small_window_NNRP2 (NRP2W); SSTTYP could be OISST, GISST and the weekly OISST (OI_WK).

The subgrid BATS land surface scheme is added in the RegCM code, and the SUBEX and aerosol/chemstry packages are modified to improve th model performance, and dust package is added recently. And most recently, we have made ready the fully parallel code.
 

The related global datasets are available HERE, you need to get special permission from UKMO if you want to use GISST.
