how to write different type of data into one obs file

hi :D
During the process of making obs files, how to write u_super_obs.nc and v_super_obs.nc into one file, easily stack?
When i set OBSNAME = u_super_obs.nc| v_super_obs.nc, ROMS only read in u, not both.

TLM: forrtl: severe(174): SIGSEGV, segmentation fault occur

hi everyone, I run IS4DVAR models. Adjust_wstress and adjust_boundary is actived, and compiling is ok. When outer =001, Inner =000, NLM proceeds well. While TLM runs, it says ''forrtl: severe(174): SIGSEGV, segmentation fault occurred'' after *_itl.nc, *_frc.nc and *_bry.nc have been read. Anyone kn...

Re: observation data rejected!

And also,
i prepare 24 gauge data along the coast, and restore it in form of grid.Then 'd_ssh_obs.m' is changed to process the grid data. The result is, only 7 diffetent gauge data writes to the obs.nc.Why?

Do u mean if Netcdf-3 is used, only Matlab version ‘2008b’ can handle it? My Matlab version is '2009a' and Netcdf-3 is used. Does it mean i have to uninstall my version and install version '2008b'?

Re: unable to open existing NetCDF file: call from: inquire

Hi, Kate. Thank you very much! I took the your suggestion and it did work.I think this is because ROMS will not read LBC values(ubar,vbar,zeta) from *_frc.nc.
