Hello,
I have run the real.exe successfully and get the wrfinputd01 and wrfbdyd01.However when I tried run the wrf.exe,the program fails immediately.and I got the error message like:
[/U] Max map factor in domain 1 = 0.00. Scale the dt in the model accordingly. D01: Time step = 90.00000 (s) D01: Grid Distance = 27.00000 (km) D01: Grid Distance Ratio dt/dx = 3.333333 (s/km) D01: Ratio Including Maximum Map Factor = 0.0000000E+00 (s/km) D01: NML defined reasonable_time_step_ratio = 6.000000 -------------- FATAL CALLED --------------- FATAL CALLED FROM FILE: <stdin> LINE: 599 start_em: p_top from the namelist does not match p_top from the input file. [U]

I
checked the namelist files and wrfinputd several times and can't find any problems.
Help requested:
Does anyone know what these error messages might mean? Is this an issue with the input data?
And how the wrf.exe get the p_top?I can't find the p_top in wrfinputd01 or wrfbdyd01. I have also read the source code of start_em.F and module_initialize_real.F but still can't understand how the wrf read the p_top.
Thanks!

In your namelist.input, p_top_requested = 1000. This is the model top of WRF, which must be lower than the highest levee of the forcing data.
Please check the data you used to produce initial condition for WRF.

Thanks for your reply! I am using the ERA5 data as the forcing data and its highest pressure is 100Pa.
I also checked the met_em* as ncdump -v PRES and its showed:
100, 100, 100, 100, 100, 100, 100, 100, 100, 100, 100, 100, 100, 100, 100, 100, 100, 100, 100, 100, 100, 100, 100, 100, 100, 100, 100, 100, 100, 100, 100, 100, 100, 100, 100, 100, 100, 100, 100, 100, 100, 100, 100, 100, 100, 100, 100, 100, 100, 100, 100, 100, 100, 100, 100, 100, 100, 100, 100, 100, 100, 100, 100, 100, 100, 100, 100, 100, 100, 100, 100, 100, 100, 100, 100, 100, 100, 100, 100, 100, 100, 100, 100, 100, 100, 100, 100, 100, 100, 100, 100, 100, 100, 100, 100, 100, 100, 100, 100, 100, 100, 100, 100, 100, 100, 100, 100, 100, 100, 100, 100, 100, 100, 100, 100, 100, 100, 100, 100, 100, 100, 100, 100, 100, 100, 100, 100, 100, 100, 100, 100, 100, 100, 100 ; }
I also changed the p_top_requested = 5000 the rerun,and gor the same error message.I am really confused about that.The information of my metfiles is posted as attach.

Would you pleas upload your wrfinput and wrfbdy file for me to take a look?
Also, where did you download the ERA5 data?
