Re: [ferret_users] select arbitary vertical levels

[Karl Smith <karl.smith@xxxxxxxx>]

Hi Jagadish,

You could regrid the second variable to the grid of the first variable.  If the only difference in the grids are the additional vertical levels, the regridded variable should be unchanged at the duplicate locations.  Then you will have two variables on the same grid.
So something like:
use dataset1
use dataset2
let regridsecondvar = secondvar[g=firstvar[d=1]]
... (work with regridsecondvar and firstvar) ...

Hi,

I have two dataset, say

1st with 6 vertical levels:  (100, 200,        500, 700, 850,        1000) &

2nd with 8 vertical levels: (100, 200, 300, 500, 700, 850, 925, 1000).

I want to vertically integrate both datesets (sepeately) and compare; but I want to integrate only over common levels. Is there a simple way to select user defined levels?

I can extract desired levels from 2nd file to a seperate file as a work around but wonder if there is a way to deal with this in ferret itself.

Thanks,

Jagadish
