This is weird. You only need to modify the roof albedo in URBPARM_LCZ.TBL. Which urban physics did you use? Could you please also attach your urban fraction map and land type (with LCZ) map?

Thanks for your response!

I am currently using the following configuration:
&physics
use_wudapt_lcz = 1,
mp_physics = 6, 6,
cu_physics = 1, 0,
ra_lw_physics = 1, 1,
ra_sw_physics = 1, 1,
bl_pbl_physics = 8, 8,
sf_sfclay_physics = 1, 1,
sf_surface_physics = 2, 2,
radt = 15, 15,
bldt = 0, 0,
cudt = 0, 0,
icloud = 1,
num_land_cat = 61,
sf_urban_physics = 3, 3,
fractional_seaice = 1,
/

I have also attached the land type map for reference.

Let me know if you need any further details. Thanks in advance!

OK, I am not sure what is going on here, but could you please:
1. try to doubling the albedo for roof, road, and building wall all together and conduct a test run to see if that makes any difference in WRF albedo? Also, which WRF albedo variable you were plotting?
2. try to use urban_physics = 2 (BEP) to see if it shows any albedo difference by your changed roof albedo experiement.

1. I used albedo1 = wrf1.variables['ALBEDO'][0,:,:] to plot the albedo map. Although I changed the albedo for the roof, road, and walls together, there was no difference in the WRF albedo.
2. I also tried using urban_physics = 2 (BEP), but there was still no difference in albedo.
 
Hey could you resolve the issue ?
I am also getting the similar error :-

The reason is the dispaly of albedo map can not show the change of the albedo of roof. If show the Temperature, there is difference.
 
Sorry for the late reply. I am not sure why, but albedo should change. Have you checked if it is in the daytime (SWDOWN >0)? or you can check the ratio of SWUPB to SWDOWN
 
One possible reason is that, ALBEDO in wrfout are not updated to include changes during the model run.

Cenlin might correct me since he knows more about ald update when urban scheme is called.
