chgr †

Location of codes
gsm/src/chgr/changers.F
Location of binary executable
gsm/bin/chgr_${INPUT_RESOLUTION}.x
Location of script executable
gruns/runscr/chgr
Usage
gruns/runscr/chgr [input_sigma] [input_sfc] [output_sig] [output_sfc] [sfc type]
Memo
environmental variable INPUT_RESOLUTION should be set.
↑

pgb †

Location of codes
gsm/src/pgb/pgb.F
Location of binary executable
gsm/bin/pgb.x
Location of script executable
gruns/runscr/pgb
Usage
gruns/runscr/pgb [start hour of forecast] [end hour of forecast] [increment]
Memo
input filename should be sig.ftXX . output becomes pgb.ftXX .
↑

grmap †

Description
Making ctl and idx files of a grib file to see by GrADS.
Location of codes
libs/etc/util_linux/grmap.F
Location of executable
libs/etc/grmap
Usage
grmap -g0 [gribfile]
Note
Variable names should be registered in grib1.kpds5.vsnXX and grib1.kpds6.vsnXX files. (If not, the names will be wrongly printed in ctl file. It can be rewritten afterwards, though)

gribmap (not ECPC utility) †

Location of codes
Location of executable
Usage
↑

grmean †

Description
calculate mean of set of grib files.
Location of codes
libs/etc/util_linux/grmean.F
Location of executable
libs/etc/grmean
Usage
grmean -s [index_list] -o [output_file]
Memo
Size of MTOTL, MMDAT, (and MDATA) should be changed for T248 or higher resolution. For T248, MTOTL=160 and MMDAT=50000000 work.
The results are not exactly same as those from GrADS or equivalent tools due to data compression. The precision can be improved by increasing KPSD(22,N) in the source codes.
