How to use LCZ data in WRF version 4.5.2

I am a beginner in WRF and want to use WRF version 4.5.2 for simulating urban temperatures. I don’t know the detailed steps to integrate LCZ data into the WRF model, and would greatly appreciate it if experienced users could provide a detailed workflow.

I have datasets from CGLC, and I have also created some LCZ maps using LCZ Generator. However, I am not sure how to incorporate these data into WRF.

Thank you all for your help; I truly appreciate it!
 
This involves both WPS and WRF:

(1) For WPS, please set

geog_data_res = 'cglc_modis_lcz+default',

(2) For WRF, you need to :

(a) activate LCZ: use_wudapt_lcz = 1;

(b) activate urban physics


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

Thank you very much for your reply! I tried doing this: first, I renamed the dataset folder to "lcz". Then, I modified the contents of namelist.wps according to your suggestions. The file geo_em.d03.nc was generated. Unfortunately, it seems that this generated file does not contain LCZ data, because when I checked the data, it shows NUM_LAND_CAT = 21. I don't know where the problem is. Here are my namelist.wps file and the output content when running geogird.exe:
