I am encountering an issue with urban canopy parameterization while running wrf.exe with the GloUCP dataset. Here's my setup and the problem I'm facing:
USING DEFAULT URBAN MORPHOLOGY
This suggests that WRF is not recognizing my custom urban parameters from GloUCP(details can be checked in rsl.out.0000).
Background
- I am using GloUCP dataset as a replacement for NUDAPT44_1km to provide urban morphology parameters.
- GloUCP is structured similarly to NUDAPT44_1km and includes 132 urban categories, which I verified by checking the URB_PARAM variable in my met_em files.
Issue
When running wrf.exe, I get the following warning:USING DEFAULT URBAN MORPHOLOGY
This suggests that WRF is not recognizing my custom urban parameters from GloUCP(details can be checked in rsl.out.0000).
What I've Checked
- met_em files:
- The URB_PARAM variable exists and contains 132 layers, matching NUDAPT44_1km's structure.
- wrfinput files:
- Variables like URBAN and LU_INDEX are present (shows in the image), but HGT_URB2D, HI_URB2D, and LF_URB2D (mentioned in the NUDAPT44_1km documentation) are missing.
My Questions
- Is WRF actually using my GloUCP dataset?
- How can I confirm if the model is using my custom urban parameters or falling back to defaults?
- How do I resolve the USING DEFAULT URBAN MORPHOLOGY warning?
- Are there additional steps required to properly integrate GloUCP with WRF?
- Do I need to modify the registry files or namelist options to recognize GloUCP's urban parameters?
