Dear WRF-Chem Community,
I am encountering an issue with my WRF-Chem simulation when the Single-Layer Urban Canopy Model (SLUCM) is enabled. I have successfully incorporated Urban Canopy Parameters (UCPs) for 60 cities in China into the GEOGRID, and I have verified that the WRF input files are correctly configured. However, when running the simulation with SLUCM enabled, the process consistently freezes at the following step:
calculate MEGAN emissions at ktau, gmtp, tmidh = 1 0.0000000E+00 1.3472223E-02
d01 2018-07-30_00:00:00 emissions_driver calling add_anthropogenics
d01 2018-07-30_00:00:00 add_anthropogenics
d01 2018-07-30_00:00:00 emissions_driver calling add_biogenics
d01 2018-07-30_00:00:00 emissions_driver not calling add_emiss_cptec
d01 2018-07-30_00:00:00 emissions_driver NOT CALLING aer add_... routines
d01 2018-07-30_00:00:00 calling optical driver
d01 2018-07-30_00:00:00 optical driver: process aerosols false
d01 2018-07-30_00:00:00 calling photolysis driver
photolysis_driver: called for domain 1
d01 2018-07-30_00:00:00 calling madronich1_driver
At this point, the simulation stalls for an extended period, and the job eventually terminates without reporting any explicit errors, which is quite puzzling. Notably, a wrfout file for 2018-07-30_00:00:00 is generated, but its size is significantly smaller than expected compared to a normal run. I have successfully run the same simulation with the same namelist.input file when UCM is disabled (noUCM), and no issues were observed.
Could anyone provide insights into what might be causing this freeze when SLUCM is enabled? Are there specific namelist settings, emission configurations, or resource considerations I should check? Any suggestions or experiences from the community would be greatly appreciated.
Thank you for your help!
