Dear all,

I have compiled the latest RegCM model for running with CMIP6 GCM outputs in my MAC laptop. I have tested with MIROC6 and it was able to pick data from concerned web server. I have also run with a linux server installed with CENTOS 8. 

So I have established a AWS cloud resource with CENTOS 8 using gcc & gfortran compiled RegCM but running CMIP6 shows the following problem.

 GLOBIDATE1 :  1980-01-01 00:00:00 UTC        
 GLOBIDATE2 :  1980-01-10 00:00:00 UTC        
 NSTEPS =           10
 NetCDF: Unknown file format                                                    
 mod_cmip6_miroc6.F90 :      435:Error opening file http://esgf-data2.diasjp.net/thredds/dodsC/esg_dataroot/CMIP6/CMIP/MIROC/MIROC6/historical/r1i1p1f1/Oday/tos/gn/v20191114/tos_Oday_MIROC6_historical_r1i1p1f1_gn_19800101-19891231.nc.:          -51
