Change in LU_INDEX and landmask (met_em->wrfinput)

[hjsung]

Hi, all.
I ran WRF with the area near the Arctic.
I got changed values in LU_INDEX and landmask.
Except for these, other variables have no problem, like sea ice and SST at the land changed point.

surface_input_source = 1 or 3
but showed the same result.

I wonder, Is there no problem with using this wrfinput?
If not, What would you recommend to try?
I also attach the namelist for wps and wrf.

I hope to get an answer; thank you.

Hi,
In your namelist.wps, you set map_proj = 'lambert'. However, for the Arctic region, it should be polar stereographic, i.e.,

map_proj = 'polar',

With this type of projection, you will also need to specify truelat1 and stand_lon in your namelist.wps.

Please try and let me know if you have any issues.

Thank you for your answer.

I tried to change map_proj='polar' before, with a focus on the Arctic. I have got the same problems with under issue.

wrfinput_d0# place inversion issue.

Hi, all. I have some questions about wrfinput. I used polar projection. The geo_em and met_em files matched what I used for Vtable (ex, ERA5, FNL) But, wrfinput_d0# became inversion from these files. wrflowinp_d0# is ok. and real.exe was success. Same result in when I changed e_we, e_sn. I...

So this time, I changed to map_mproj='lambert' with the near area of the Arctic.

Hi,
I have run WPS using your namelist.wps. Below is the error message I got:

Warning: Northern edge of grid must be at least 5 grid points from mother domain!
Warning: Inner nest (domain = 2) is not fully contained in mother nest (domain = 1)!
For the current setup of mother domain = 1, you can only have a nest of size 841X286. Stopping Program!

This indicates that the nesting is not set correctly. Please correct the domain setting issue.

If I run over a single domain, I got the plot shown in the attached file. It shows the correct domain setting for your D01.

Is this what you saw in your result? How did you produce the figures you attached in your post?
