Fails to perform PREPBUFR data assimilation

Dear Colleges,

I am trying to perform conventional data assimilation with the WRFDA v4.0. I have the data in PREPBUFR format (ob.bufr file). Please, also find attached my namelist.input and fg files. The WRFDA does not show any errors (log.out), but no data assimilation is performed.

Please use this link to download my files:

Can you help me with this issue?

It looks like WRFDA is looking for ob.ascii instead of ob.bufr. wrfvar3::eek:b_format should be set to 1 for bufr instead of the default 2 for ascii.
