    Question about running the Urban BEP model in WRF

    Hi everyone, I have geo_em files generated by WPSv4.4 that include urban building information. Using Python scripts, I converted the "LU_INDEX" and "LANDUSEF" in the geo_em files to make them compatible with WPSv4.5. After running the full workflow in WRFv4.5.2, the results suggest that building...
