I have set the initial boundary conditions of ROMS to N=16, so the seawater temperature, salinity etc. data in the his file is also divided into 16 layers. I know that the depth of seawater under the same water layer varies when the topography varies. So I would like to know how can I get the data above 400m water depth by matlab? How do I get the seawater temperature and salinity data for a certain point at different water depths?
Thank you very much for your help!
