Dear All, 
I downloaded the GFDL-ESM2M rainfall data (pr_Amon_GFDL-ESM2M_historical_r1i1p1_186101-186512.nc) from the following website

http://clima-dods.ictp.it/data/d8/cordex/CMIP5/monthly/hist/GFDL-ESM2M/pr_Amon_GFDL-ESM2M_historical_r1i1p1_186101-186512.nc

But I am not able to open this file in grads.
The following errors are coming

While ncdump
