Dear All,

I got strange errors form gen_be_etkf.exe in WRFV4.0.3 and WRF4.1. However, it works fine in WRF3.9.1.1.

The variable of "proj_mn" gets a value of "NaN", indicating that something is wrong. Besides, a error "NCVPT: : NetCDF: Start+count exceeds dimension bound" occurred at the end

Full information is given as follows. T

Thanks in advance.
