interpolation
Added by pooran khedri almost 7 years ago
Hello all,
Is there a way to interpolate data on vertical? I downloaded the salinity and temperature of 73 sigma level I need to have 23 sigma level.
I was wondering for any suggestions as early as possible.
Best regards,
Pooran
hi!
CDO supports plain depth levels for ocean with operator intlevel. I don't know what your z-axis is about - an upload would help

hi,
Thank you so much for your reply, In attachment I have sent my file, with cdo I could interpolate in horizontal direction, I also need to interpolate in the vertical direction, This file has 51 sigma layer and I need to interpolate it to 20 layer.
Thank you in advance.

sorry,I have forgotten to attach my file.
Here is my file
this seems to be a plain z-level axis, so you can interpolate it with the intlevel operator like this
cdo intlevel,1,5,10,20,30,50,100,200,500,3000 <ifile> <ofile>
Thank you so much for your help.

Dear ,
Actually,The σ-coordinate is defined by σ = z/D where D is the total depth. where σ varies between 0 at the bottom and 1 at the surface.
