Hi Gazi and Mehran,
I've been running the CMIP6 MPI scenario without downloading the data, using the following in the .in file:
&globdatparam
ibdyfrq = 6,
ssttyp = 'CMIP6',
dattyp = 'CMIP6',
gdate1 = 2015120100,
gdate2 = 2100120300,
dirglob = 'input',
inpglob = '/REGCM_GLOBEDAT',
/
&cmip6param
cmip6_inp = '
https://esgf3.dkrz.de/thredds/dodsC',
cmip6_model = 'MPI-ESM1-2-HR',
cmip6_ssp = 'ssp585',
cmip6_variant = 'r1i1p1f1',
cmip6_grid = 'gn',
/
(This needs the latest version of RegCM5)
Hope that helps a bit.
Cheers,
T
