Fortran programs that combine the tiled GrADS output from CM1 into one file: valid for cm1r12 and later versions
(used for processing the output from CM1 when using MPI processing and when the GrADS output format is selected):

Note: these new, more efficient "combine" programs have been released with cm1r16:

• combine_MPI_s.F: combines scalar (*_s) files
• combine_MPI_u.F: combines u files
• combine_MPI_v.F: combines v files
• combine_MPI_w.F: combines w files

Usage: compile with a fortran compiler. Then, run the program, and answer all the questions. Note: you will need to have a copy of your GrADS descriptor file (i.e., files ending in ".ctl") in the same directory.

Output: two files are created: a new descriptor file (cm1out_MPI.ctl) and a new GrADS data file.

Fortran program to combine the tiled netcdf output
(same as above, but for netcdf output format)

• combine.F: fortran program (cm1r11 ... contributed by Dan Kirshbaum, U. Reading)
• combine_r12.F: fortran program (cm1r12 and later versions ... contributed by Lou Wicker, NSSL)
• compile: script used to compile the program
