[Wrf-users] Adjusting vertical levels

[Feng Liu]

Jason,
The error message you provided indicates the num_metgrid_levels for input data is 27, but you set it as 65 in your namelist.input. The mismatched vertical levels resulted in the crash, I think. You may have different vertical levels as defined by e-vert, and WRF will do interpolation from num_metgrid_levels to e-vert. However,  num_metgrid_levels  in the namelist.input should be the same as input data. Just straightforward double check this number from your met_em.d0* file. I think it should be 27 rather than 65. Hope that is helpful.
Feng

Dear Feng,

Somehow WRF portal is automatically changing num_metgrid_levels to a number equal to e_vert when editing ETA levels. In fact that is not the case and there are only 27 levels in the input files as you suggested. Seems like it's worked a treat. Thanks.

Hi Jason,
The problem is the number of vertical level in the namelist.input, 65, does not match the number (27) in the input data of met_em.d0*_had. Try to change num_metgrid_levels = 65 into  num_metgrid_levels = 27 in the namelist.input. Then it should work.  Thanks.

Dear all,

I am trying to arrange vertical levels within a simulation but the simulation ends at start up. Below is the error message I get from any rsl.error files. I am guessing that there is a mismatch between boundary condition vertical levels and the levels I am trying to set up. Is this something that settings can fix or do I have to look up boundary data with higher vertical resolution? If so, can you please suggest high resolution (vertical) boundary data sources?

rsl.error:

Kind regards,

Jason
