[MITgcm-support] filter for cubesphere-gridr-corners

[Yuan Lian]

Hi, Ed

I am trying to add an extra corner filter (like zonal filter as a polar 
filter) to the eight cubesphere-grid corners. I am thinking to add this 
filter as a subroutine so its strength is adjustable. The reason why I 
will do this is because I found the corner effect is very obvious in my 
atmospheric model. Could you please give me some instructions to do 
this? Thanks a lot!
