Probelm about data assimilation

#1 Unread post by jiangyuwu »

When i try to run ROMS with data assimilation, model will be not converge and the float value written into TLMNAME and ADJNAME will grow larger and larger. Finally, the program terminated with the error msg: Numeric conversion not representable.

I googled this error msg.
If the float value is larger than HUGE(r4), the nf90_put_var function will throw this error.

Can somebody give me some idea on how to solve this problem? Thanks a lot.
