[MITgcm-support] linear growth of runoff

[Dmitri Leonov]

Hello Patrick,

Please let me know what exactly it was that you found wrong in my input 
files. I've tried setting the runoffperiod to zero as you suggested but 
the runoff still seems to be growing linearly - so the problem is not in 
the time-interpolation but somewhere else. This is not architecture or 
compiler specific as I originally thought it might be: just got same 
results on a linux pc using g77.

Maybe I'm not allowed to have closed boundaries when I have a non-zero 
E-P-R, so it's not a good test? What do you mean by balancing E-P-R 
fields? In the actual experiment I have an open boundary.

If there is in fact some kind of bug there I thought some people other 
than myself might be interested in looking into it. Otherwise I'll need 
to find out what exactly was wrong with my set-up.

Regards,
Dmitri.
