Re: [ferret_users] spatial smoothing with unequal sized grid cells

[Ansley Manke <ansley.b.manke@xxxxxxxx>]

Hi Paul,
Ferret doesn't have tools to do anything like that taking into account the curvilinear grid.

You could apply one of the smoothing transformations you mention,  and the mechanics of the operation would work fine, but it would be applying the smoothing in index space. As in the case of an irregularly-spaced rectilinear grid, the results wouldn't be consistent with applying an operation over ranges of longitude/latitude.

Hello,

I would like to smooth my results of an ocean variable spatially. The variable is on a high-resolution curvilinear grid and I would like the grid to remain the same; however, I would like a smoothing of the variable by looking at values in a (say 3x3) box around every point. The expressions @SBX, @SBN, etc., note that they are for equally spaced axes.

Can this be done?

Many thanks,

Paul
