merge files one with one time and one with 6-hourly data CDO version 1.5.6.1

Added by cynthia hays over 11 years ago

Hello,

I'm new to cdo and I want to use ml2pl to get pressure levels. The only surface geopotenital (orography) I have is in a fixed file (one time). How do I get this variable "merged" with my 6-hourly files so that I can use it to calculate pressure levels.

Thanks

Cindy

Sorry - I mistakenly added this as an issue.

Hi

I guess, you also need surface pressure in addition to orography, to interpolate the required variable to pressure levels.

Anyway to merge those, you may try:

1. cdo merge ifile1.xxx orography.xxx surf_pressure.xxx output_file.xxx

OR

2. cdo cat ifile1.xxx orography.xxx surf_pressure.xxx output_file.xxx

OR

3. cdo copy ifile1.xxx orography.xxx surf_pressure.xxx output_file.xxx

If your input file format is GRIB, you can simply use linux "cat" command to merge those, i.e.,

cat ifile1.xxx orography.xxx surf_pressure.xxx > output_file.xxx

Hope this helps!

Cheers,
J.
