Dear All,

Sorry for disturbing you.

Errors occur when I run the RegCM4-CLM4.5 over a large domain.

It seems that the errors are due to the large domain size.

Does the CLM support the Netcdf4？

What can I do to fix this problem?

***********settings**************:

enable clm45

enable netcdf4-hdf5

 jx     = 450,   ! This is number of points in the E/W direction

 kz     = 30,   ! Number of vertical levels

 nsg    = 1,    ! For subgridding, number of points to decompose. If nsg=1,

                ! no subgridding is performed. CLM does NOT work as of now with

                ! subgridding enabled.
