WRF-4.4 modified URBPARM_LCZ.TBL doesn't work


New member
Hello everyone,
1.When I modified the URBPARM_LCZ.TBL parameter, it did not work. I need to modify the FRC_URB2D parameter and BUILD_HEIGHT parameter. In URBPARM_LCZ.TBL, set FRC_URB2D to 0.1 and BUILD_HEIGHT to 5, but the FRC_URB2D variable and BUILD_HEIGHT variable in the wrfout file is as shown in the figure. By the way, i found wrfinput file has FRC_URB2D and BUILD_HEIGHT value same as wrfout file! So how to make the URBPARM_LCZ.TBL file take effect.
2.When I put sf_urban_physics = 0, where do the albedo, emissivity and heat capacity of LCZ1-10 input, how should I output these variables for viewing?
Thanks for any help!
