…tax2T. The real problem is most likely difference between U and T mask.
Initializing zetax2T and etax2T avoid spurious values when they are used.This is a cure but maybe only for the immediate symptoms. |
The averaging across different masks is something we made need to extend. The underlying masks used are tmask, umask, nmask, emask for the "S" averaging. It could be that we need some other averagers that, for instance, send in the mask and/or weight as part of the call. We should review all the average calls in the CD implementation and make sure we understand what is needed vs what is currently being done. |

Looks good, this seems like a good practice to initialize to zero to avoid unexpected results. Perhaps in FORTRAN it does not automatically initialize allocable arrays to zero?
There are pluses and minuses to this approach. By setting arrays to zero, you allow the code to run to completion. But I think that something is still probably wrong. A value is not being computed somewhere where maybe it should. If initializing to zero is "correct", then that's great. If it's covering up another problem, then the benefit of this fix is mixed. It would be good to understand better whether the masked computations are all correct, and what may need to change to fix this properly. |
@apcraig is right this hides the fact that the icepoints with the T mask is a subset of the umask due to the fact that umask assigns icepoints to places where the four neighboring points can include up to two landpoint. Tmask requires that all points are ocean and have some ice. Despite that the mask captures these by multiplication there are some places where the absolute value is very small or big and sometimes NaN. The question is then if c0. is a good "missing value" value for the viscous coefficients. |
What's the status of this PR? Should it be merged as-is, or is there some uncertainty about whether this is the right thing to do? |
I'm waiting on some consensus about whether this should be merged or not. I'm happy to go either way. |
