<p><font size="2">I'm still reviewing the NetCDF documentation, but
so far it seems the calling program (WRF) is supposed to pass a flag to
NetCDF to turn 64-bit offset on. So it's also a WRF issue.<br>

And I'm using NetCDF 4.0.1. <br>

This is a netCDF issue, not a WRF issue. Look at the netCDF<br>
documentation for notes on large file support, or possibly update your<br>
version of netCDF.<br>
