why the ajoint model need climatology input

#1 Post by simion1232006 » Tue Jun 30, 2015 8:14 am

Hi everyOne,

I am testing the ROMS strong constrain data assimilation model. I got a interesting error that asking me to prepare climatology inputs . This is only required for the updated ROMS version. For the version older than ROMS3.4 there is no such error. I am curious why it requires climatology inputs for version later than 3.4? Isn't observational inputs enough for data assimilation?
Any ideas?

Kind Regards
