reorder the dimensions in a netcdf file

Added by nazanin tavakoli almost 4 years ago

Hello,
I have a question about reordering the dimensions with ncpdq. The dimensions in my file are in (lengthd,time, langitude, latitude) order like:
lengthd = 10
time = 12 (UNLIMITED)
longitude = 720
latitude = 360

I need them in (longitude, latitude, time,length) order.

I tried the following:
ncpdq -a -longitude,latitude,time,lengthd f1.nc f3.nc

now, I got an order of dimension like below, the lengthd is eliminated, and the longitude became UNLIMITED, and reordering did not happend

Dimensions:
           time      = 12
           longitude = 720   (UNLIMITED)
           latitude  = 360

could anybody help me?

This is not a CDO problem. Please, read the NCO doc about ncpdq or google your question, I'm sure you will get the information you need immetdiately.

yes, you're completely right, I have searched a lot but my code has some problem. When I was searching, I found that a person asked about reordering in this group ( I have sent the link here), so I asked my question maybe somebody knows s.th and help me.

Even you have suggested me these 2 codes in this link (https://code.mpimet.mpg.de/boards/2/topics/10494?r=10875#message-10875) two month ago.

ncpdq -O -a lon,lat,time 1901.nc tmp.nc
ncks -O --fix_rec_dmn lon tmp.nc 1901reorder.nc

I usually try to help as much as I can, but I'm not an NCO expert, so it's on you to search for an answer.

yes, I know. You always answer my question carefully.
Thank you very much
