Issue with overlap region in cdfmean ?

[pmathiot]

Hi,

In cdfmean, the default is to use the 3d mask in meshmask. In this case, the overlap region are not masked. So when we are computing a global mean the overlap region is double counted. I suggest to read in addition maskutil and multiply both mask for each level (example available here)

I agree the suggested fix could be improve: the use of maskutil should only be done is no custom mask used.

Hi,

I lately came across the same issue and found your solution very helpful. Also the -surf option makes it so much easier e.g. for SSH. Thank you!
To overcome the issue you mention in the end, I just created a new cdfglobalmean routine using maskutil and left cdfmean un-altered.
