Hello,

From a quick glance it seems that you may not have properly linked your observation file. After you've run obsproc on your little r files, you should get observation files. With those files, you then need to link them to ob.ascii or ob01.ascii if you have more than one timestep.

Thank you,
JeremyB

thank you sir for your response

I previously thought that if you want to assimilate himawari-9 data there is no need to link surface observation data such as little_r. After reviewing your opinion about my problem “No AHI file Found” is it still necessary to link observation data? and before i renamed my file AHI with L2AHICLP

I attach below the namelist files that might be considered, I really need help to solve this problem.
