namelist.input

Table of contents

背景

  • namelist.input同時是控制real和wrf的名單，其中起訖時間、網格編號，會隨著執行批次而異，此處以變數填入，以備各個批次執行時可以隨時以sed替換。

namelist.input模版說明

起迄時間之設定

  • 批次執行的起訖時間，日期保持變數狀態，以便自動執行時能隨時替換。
    • SYEA, SMON, SDAY:起始年、月、日
    • EYEA, EMON, EDAY:結束年、月、日
    • 起訖小時：為方便後續光化學模式的執行，一律設為00UTC

wrfout輸出變數項目之增減

  • wrfout輸出哪些變數，是在Regisry/Registry.EM檔案中指定的(IO設定值含有h)，如要修改，可以修改該登記檔，clean -a、configure、compile重新編譯，如範例
state    real    CLDFRA2      ikj    misc     1         -      h        "CLDFRA2"             "CLOUD FRACTION"
state    real    RAINPROD     ikj    misc     1         -      h        "RAINPROD"            "TOTAL RAIN PRODUCTION RATE"       "s-1"
state    real    EVAPPROD     ikj    misc     1         -      h        "EVAPPROD"            "RAIN EVAPORATION RATE"            "s-1"
  • 如不重新編譯亦可在nmelist.input檔案中設定
    • my_file_d01~2.txt為文字檔，每個domain必須要有一個檔案。內容如後。
&time_control
iofields_filename = “my_file_d01.txt”, “my_file_d02.txt”
ignore_iofields_warning = .true.,
/
  • my_file_d01.txt的內容
    • +、-增加或減少之標籤
    • i for input/h for history(output)
    • 0 for default, number for stream number ` variable names
-:h:0:RAINC,RAINNC
+:h:0:EDUST1,EDUST2,EDUST3,EDUST4,EDUST5
