Re: [ferret_users] Subsampling

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

Hi Vincent,
There are several sampling functions in Ferret, one of which will help you. Take a look at SAMPLEXY and SAMPLEXY_CURV. Or say

yes? show function samplexy* 

to see them all. Which one you need depends on what the grid of the data is like.

If you need a hand figuring out how to use one of these, then please write back - Is the 2D field on a rectilinear grid?  Or do the longitudes and latitudes represent a curvilinear grid?  If you open the datasets, what does the output of SHOW DATA look like?

Dear users,

I got 3 files, one with a 2D field, an other with the respective longitudes and the last one with the respective latitudes. I would like to subsample my 2D field on a smaller geographical region. What would be the best approach to use?

Thanks for any tip,

Cheers, Vincent
