Hi, everyone! As for my research purpose, future hourly weather data including air temperature, relative humidity, solar radiation, wind speed and direction is required. I am learning RegCM to downscale GCMs. However, the user mannual is a bit simplified for a beginner like me. I am wondering that for RegCM to donwscale GCMs from CMIP6? If so, what kind of GCM should I prepare (abbreviation such as ta, rsds, etc.)? And which choice I should specify regarding "ssttyp" and "dattyp" in the setting file?

Here's the relative part in the Readme file:

ssttyp = 'EIN75', ! Type of Sea Surface Temperature used

! One in: GISST, OISST, OI2ST, OI_WK, OI2WK,

! FV_A2, FV_B2, EH5A2, EH5B1, EHA1B,

! EIN75, EIN15, CCSST, CA_XX, HA_XX,

! EC_XX, IP_XX, GF_XX, CN_XX, MP_XX

dattyp = 'EIN75', ! Type of global analysis datasets used

! One in: ECMWF, ERA40, EIN75, EIN15, EIN25,

! ERAHI, NNRP1, NNRP2, NRP2W, GFS11,

! FVGCM, FNEST, EH5A2, EH5B1, EHA1B,

! CCSMN, ECEXY, CA_XX, HA_XX, EC_XX,

! IP_XX, GF_XX, CN_XX, MP_XX, CMIP6

! with XX for CMIP5 datasets in 26, 45, 85

! For CMIP6, fill the cmip6param namelist

! CMIP6 model selection

!

&cmip6param

cmip6_model = 'MPI-ESM1-2-HR',

cmip6_inp = 'https://esgf3.dkrz.de/thredds/dodsC',

cmip6_ssp = 'ssp585',

cmip6_variant = 'r1i1p1f1',

cmip6_grid = 'gn',

Any help would be greatly appreciated. Thank you!
