Total number of obs=0 in da_wrfvar.exe

Hi everyone,

I'm recently running WRFDA trying to assimilate our surface wind observation and Wind LiDAR data to the simulation. I generated ob.ascii successfully but when I try to run da_wrfvar.exe it always tells me no observation being read, analysis field=0 and J0=0 in the end. I try to adjust the field records/ qc flags in ob.ascii, checked the time window, adjusted my WRF e_vert to 43 to match the default be.dat.cv3, but none of them works. I also tried check_max_iv = .false. but all the observation still been read and rejected without any extra information(check_max_iv result is empty, no used/rej info as in the tutorial).

I’ve attached the full log from da_wrfvar.exe and my namelist setup for your review. Any suggestions about what to look for next, or potential causes I might be missing would be greatly appreciated. Thanks in advance for your time and help.

Best regards,
Haoyue
