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
• found in utils/
• 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
• found in utils/netcdf/
  • 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
