I'm running the I4DVAR for my real application. There is an error which is related to the netcdf filename. I'm comfused about this. My ROMS version is 4.0, which is the newest one. The assimilation process runs pretty well. However, it says that "unable to open existing file". I have checked the ...

Thank you for your reply! The model can read observation data in 4DVAR successfully. However, there still are some errors during my model running. The error information is "Negative Ritz value found". The full log file is appended at the end. Could you please help me figure out this question ...

I have run the I4DVAR tutorial in WC13 application successfully to help me understand ROMS 4DVAR. Then, I built up my own NLM application successfully without variational data assimilation. However, when I define I4DVAR in my header file to open the variational data assimilation in my application ...

Hi, everyone. I do some 4DVAR tests in my own application. When I activate the I4DVAR option which is similar to the WC13 application, the observation file I made is always not read by ROMS. The errors are as follows: Number of State Observations Processed: ObsTime = 16816.0000, 2016-01-16 00:00:00 ...

Yeah, while I just want to close the right-hand side for some tracers in my application. For example, I don't want to close any term for the tracer temperature and salinity. I want to set the right-hand side to zero for dye_01 or biological tracer, for example. What I want to do is add a new cppdef ...

Hi, I'm a beginner at ROMS modeling. I have a question about the model. I want to know how to close the diffusion term for tracer. In ROMS, the tracer equation is like follows: tracer.png In my application, I only need the advection and local term in the tracer equation. In other words, I just need ...
