  • [GSM] What is difference between sigit and sigitdt? -- kei 2006-12-28 (Thu) 14:54:55
    • Both are used for restart, but sigit is time=t, whereas sigitdt is time=t+dt. -- kei 2006-12-29 (Fri) 00:17:08 10:05:31};
  • [GSM] What does sigma-level data contain? -- kei 2006-12-28 (Thu) 14:55:48
    • See here -- kei 2006-12-29 (Fri) 10:09:46
  • [GSM] How is sigma-level data converted to grid data? -- kei 2006-12-28 (Thu) 14:56:33
    • by subroutine subpgb.f -- 2007-04-23 (Mon) 16:48:52
  • [GSM] Only pgb-files (pgb.ftXX) and flx-files (flx.ftXX) are grib format. sig- and sfc-files something different (simple binary??)... -- kei 2006-12-28 (Thu) 20:50:22
    • Only postprocessed files are grib format. sig and sfc should be binary files. -- kei 2006-12-28 (Thu) 20:50:49
  • [GSM-gsm] When ENDHOUR in gsm script is changed to 144 and INTSFCX, INTSIG, INTSFC, INTPOST, and INTRESTART are changed to 12, the simulation fails in the last part. (only sig.ft144 is created, but NO flx.ft144, pgb.ft144, and sfc.ft144) -- kei 2006-12-28 (Thu) 20:51:29
    • Due to lack of necessary data (SST). In default, only one file with one-day timestamp was selected. Forecasting program (fcst) allows 5 days with no corresponded time stamp. So, it stops in 6th day simulation. -- kei 2006-12-28 (Thu) 20:51:47
  • [GSM] In post processed diagnostic file (flx.ftXX), soilw for z=1-3 is not shown. z=4 is OK. -- kei 2006-12-28 (Thu) 20:52:49
    • Use grib2ctl.pl instead of grmap -- 2007-04-23 (Mon) 16:49:24
