Background Error Statistics in WRFDA


New member
I have used two-way nested domains like 12 Km and 4 Km for WRF3DVAR simulations, and after that, I have calculated Background error statistics for 12 km to generate cv6 background error statistics and I got the be.dat file. Here my question is: how can we use a 12 km be.dat file for 4 km? If anyone knows, could you help me in this regard?
