ncrcat concatenates record variables across an arbitrary number of input files. The final record dimension is by default the sum of the lengths of the record dimensions in the input files.
Input files may vary in size, but each must have a record dimension. The record coordinate, if any, should be monotonic (or else non-fatal warnings may be generated). Hyperslabs of the record dimension which include more than one file are handled correctly. ncra supports the stride argument to the -d hyperslab option for the record dimension only, stride is not supported for non-record dimensions.

ncrcat 8.nc 8589.nc
ncrcat -n 5,2,1 85.nc 8589.nc
Assume the files
ncrcat -d time,11,13 85.nc 86.nc 87.nc 8512_8602.nc
ncrcat -F -d time,12,14 85.nc 86.nc 87.nc 8512_8602.nc
The following uses the stride option to concatenate all the March temperature data from multiple input files into a single output file
- ncrcat -F -d time,3,,12 -v temperature 85.nc 86.nc 87.nc 858687_03.nc
Assume the time coordinate is incrementally numbered such that January, 1985 = 1 and December, 1989 = 60. Assuming ?? only expands to the five desired files, the following concatenates June, 1985--June, 1989:
- ncrcat -d time,6.,54. ??.nc 8506_8906.nc

HOMEPAGEThe NCO homepage at <http://nco.sf.net> contains more information.
SEE ALSOThe full documentation for NCO is maintained as a Texinfo manual called the NCO User's Guide. Because NCO is mathematical in nature, the documentation includes TeX-intensive portions not viewable on character-based displays. Hence the only complete and authoritative versions of the NCO User's Guide are the PDF (recommended), DVI, and Postscript versions at <http://nco.sf.net/nco.pdf>, <http://nco.sf.net/nco.dvi>, and <http://nco.sf.net/nco.ps>, respectively. HTML and XML versions are available at <http://nco.sf.net/nco.html> and <http://nco.sf.net/nco.xml>, respectively.
If the info and NCO programs are properly installed at your site, the command
- info nco
should give you access to the complete manual, except for the TeX-intensive portions.
