Hi Sir/Madam,

I am a WRF-Chem model user and building the model on different machines/clusters. I wonder if different compilers or even different versions of same compiler would affect my simulation result. Take two cases for example, I build WRF-Chem on machine1 with intel fortran compiler and on machine2 with gfortran. Also, I build this model on machine1 with gfortran 4.8.5 and on machine2 with gfortran 8.3.1.

For your information, we will use the same version of WRF-Chem, that is WRF4.2.1 and WPS4.2.

Please let me know if anything is missing.

Many thanks,
