[ferret_users] select arbitary vertical levels

[jagadish karmacharya <j_karmacharya@xxxxxxxxx>]

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
