Hello everybody
I am setting up a nested (4 domain) wrf-chem 4.2.2 run.
I use the following sequence of processes for getting the additional inputs:
a) create wrfbdy_d01, wrfinp_d01-d04 and wrflowinp_d01-d04 using real.exe
b) use bioemiss to generate wrfbiochemi_d01-d04
c) use real to update wrfbdy_d01 and wrfinp_d01-d04
d) use mozbc to generate BC + ICs for D01-D04
e) launch wrf.exe to generate the results
