[RegCNET] Help for reading CCSM output

[Moetasim Ashfaq]

Hi,

I have sent multiple emails regarding CCSM-RegCM over the past couple  
of months. I am copying my last email here. Also, the correct code is  
attached.

Bi: Could you please update the CCSM code with the attached one in the  
RegCM3, which is available on  web.

Hi Nguyen,

In addition to the instructions in the forwarded message below, you  
also have to make following changes.

Line 261 in CCSM.f
1948 should be changed to the start year of time "units" in CCSM data.  
This can be checked by using ncdump on any of the ccsm netcdf files.
Line 438 in SST_CCSM.f
atime should be equal to the number of time steps in your SST data file.
