Hi Vinit,

It sounds like you want to examine ocean data. Assuming you have a
netCDF file of the ocean data, you would do something like this:

a = addfile("sample.oceandata.nc","r")
temp = a->T(:,21,:,:) ; assume data is in time,lev,lat,lon format

or this

a = addfile("sample.oceandata.nc","r")
temp = a->T(:,{3372},:,:) ; assume data is in time,lev,lat,lon format
                            ; use coordinate subscripting to choose 3372m
                            ; level

If you haven't already, I suggest you download and look at the NCL
mini-language manual here:
http://www.ncl.ucar.edu/Document/Manuals/

Specifically take a look at page 5 (Dimensions and Subscripting) and the
File I/O section, pages 9-11.
Good luck,
Adam
