_Re:_[MITgcm-support]_Advection_schemes

[Patrick Heimbach]

Hi Petter,

sorry I oversaw your reply
(I am CC-ing to mitgcm-support and suggest
that you always send to that list).

Re. your question I think you forgot to also specify
 tracerAdvScheme = 33
in your data file.
Can you try and see whether that gives the
desired results?
