geogrid.exe didn't work with CGLC_MODIS_LCZ data

[Tony]

Hi forum,

I have been trying to use the CGLC_MODIS_LCZ data. When I re-linked the GEOGRID.TBL with GEOGRID.TBL.AWR_LCZ, and run the geogrid.exe it shows the error(geogrid.log):

INFORM: For LANDUSEF, couldn't find interpolator sequence for resolution default.

but when I delete the content about CGLC_MODIS_LCZ, the geogrid.exe excecuted successfully.

I also tried to add entries to the original LANDUSEF section like this (screen shot attached):
the geogrid.exe worked but the final geo_em.d04.nc only have 21 categories instead of 61.

The WPS V4.5 is used.

Could you please take a look at it? Thanks.

Best,
Tony

Hi Tony,
Can you also attach the full GEOGRID.TBL you're using? Can you also issue the following:

ls -ls /public1/home/sch3314/soft/Static/WPS_GEOG >& ls.txt

And then from inside your WPS directory, issue

ls -ls geogrid/GEOGRID.TBL* >& geogrid.txt

and attach the ls.txt and geogrid.txt files, as well? Thanks!

Hi kwerner,

Thanks for your reply. I have attached the files you mentioned.

I added a extension (.txt) to the GEOGRID.TBL so I can attach it here.

The files are attached. Thanks.

Thank you for sending those files! It looks like the problem is that, for some reason with this particular data, you need to specify it in the resolution for every domain. So if you change "geog_data_res" to the following in your namelist.wps, it should get past this error:

geog_data_res = 'cglc_modis_lcz+default', 'cglc_modis_lcz+default', 'cglc_modis_lcz+default', 'cglc_modis_lcz+default',

Thanks kwerner, this solved the provlem perfectly. now the geogrid data can be generated normally.

If I wanted to use cglc_modis_lcz data, but didn't turn on the city parameterization scheme, would it work and get reasonable results?

Since this is a different question than the original post, please open a new thread and post your question there. Thanks!

Hello!!

I am also facing the same issue as Tony. I attached all the files. Can you please look into it and provide some suggestions?

Thanks!

Hello!!

Per your geogrid.log, geogrid ran without any errors, which is not the same issue Tony was having. What specific issue are you having?

If you are getting any sort of error at any point, one suggestion: It looks like you have the GEOGRID.TBL linked to GEOGRID.TBL.ARW, which is then linked to GEOGRID.TBL.ARW_LCZ.

1 lrwxrwxrwx 1 sadislam its-rs-user    15 May 22 23:05 geogrid/GEOGRID.TBL -> GEOGRID.TBL.ARW
1 lrwxrwxrwx 1 sadislam its-rs-user    19 May 22 23:05 geogrid/GEOGRID.TBL.ARW -> GEOGRID.TBL.ARW_LCZ

Try just linking GEOGRID.TBL to GEOGRID.TBL.ARW_LCZ.

• Though geogrid ran successfully, the log shows some warning signs, which I thought could be some error (geogrid_log). Should I just ignore this warnings?
• I linked GEOGRID.TBL to GEOGRID.TBL.ARW_LCZ using this command: ln -svf GEOGRID.TBL.ARW_LCZ GEOGRID.TBL

Does it look okay now (geogrid_txt)? However, even after linking in this way, I am still seeing the warnings mentioned in the geogrid_log image.

I tend to believe that the warnings don't really matter. Please move on to run metgrid, real and wrf. Let me know if you have any trouble during the above processes.
