WRF(Weather Research and Forecasting Model)関連。

WRFにて処理をしようとした時に、./real.exe実行時に以下のようなエラーが出た。

-------------- FATAL CALLED ---------------
FATAL CALLED FROM FILE:  <stdin>  LINE:     849
 input_wrf.F: SIZE MISMATCH:  namelist ide,jde,num_metgrid_levels=          85          64          27 ; input data ide,jde,num_metgrid_levels=          85          64          32
-------------------------------------------
--------------------------------------------------------------------------
MPI_ABORT was invoked on rank 0 in communicator MPI_COMM_WORLD 
with errorcode 1.

NOTE: invoking MPI_ABORT causes Open MPI to kill all MPI processes.
You may or may not see output from other processes, depending on
exactly when Open MPI kills them.
--------------------------------------------------------------------------

上記のエラーにてnum_metgrid_levelsの値が27と32というMISMATCHが発生している。

関連しそうな情報は以下のようだ。

Major improvements include:
...
Preliminary date for the upgrade becoming operational is May, 17th 2016.

GFSのバージョンアップでnum_metgrid_levelsが変更になったようだ。
変更データは2016年5月17日以降のデータなのだろう。

対処

namelist.inputの以下の設定を変更する。

変更前
num_metgrid_levels = 27
変更後
num_metgrid_levels = 32
