WRF crashes unexpectedly when using RUC LSM

Hi everyone,


I am currently running some simulations in complex terrain. I have successfully run and validated a simulation using the Noah-MP Land Surface Model without any issues. Now I want to study the effect of using different LSMs. When I try to use the RUC LSM, wrf.exe crashes immediately after the first call to the SFCLAY scheme, giving a segmentation fault. I am using sf_sfclay_physics = 1, the revised MM5 Monin–Obukhov scheme. I tried allocating more resources for the simulation but it doesn't affect the error.


I am looking to run RUC with 6 or 9 soil layers. I use ECMWF-IFS forecast input data, which has only 4 soil levels, but as far as I understand, real.exe should be able to interpolate the missing layers from the met_em files. This seems to work, since the generated wrfinput file has the required 9 soil layers and the soil moisture and temperature values appear reasonable. The simulation also runs perfectly when using the Noah-MP LSM, which uses only 4 soil layers.


I wanted to ask whether this is a known issue and if there are any extra steps required to use RUC with this kind of input data or surface layer configuration, since I was not able to find any relevant information online. Otherwise, I would appreciate any ideas on where this problem might originate.


Thanks in advance!
