Re: Quetions about solar radiation as ROMS input forcing

Hi,
For my experience, if you defined bulk_fluxes in your cppdefs, you should use downward solar radiation.

If not, you should use the net one.

Hope that makes sense.

Re: Can ROMS read in albedo field from external files?

I tested the ALBEDO_FILE.
It just works as the forcing files, which need the time variable.
To use a temporal invariant field, just provide the albedo at starttime and endtime (2 time index). I guess ROMS will do a linear interpolation to the albedo value.

Re: Can ROMS read in albedo field from external files?

Thanks again! I am using the reflectance values from MODIS MYD09A1, and mapping them to my model grid. I am modelling the Yellow Sea with Solar radiation from ERA-interim(0.75 degree resolution). Coastal region is always being over heated, I was suggested to look into the albedo distribution as the ...

Re: Can ROMS read in albedo field from external files?

Sorry Kate, I think i still need you help on how to use ALBEDO_FILE.

Should I provide it as a forcing file? Is it able to use a constant albedo field or the file need to be like the forcing files with time index?

Thanks a lot!

Can ROMS read in albedo field from external files?

Hello,

I wonder if I can map albedo values (from MODIS) to ROMS grid, is there a way to read in the albedo value when the model runs?

Thanks in advance for any suggestions.

Radiation temporal resolution and overheating problem.

Hi, I am implementing a high resolution model(1km horizontally) with 40 vertical levels in the Yellowsea and Bohai sea. The model was developed by somebody else in the beginning and I am trying to optimize and validate the model. As I am kind of new to ocean modelling, so I need to seek advice on th...

Re: Is there a balance between SSH and currents?

Thanks for your rely there! I will try to have a look at the ssh at the open boundary. This has been a problem for me for a long time. One of my supervisor suggested that the ADCP may have some uncertainty in compass so it might be bad to compare the u and v velocity, another way is to compare the m...

Is there a balance between SSH and currents?

Hi, I am running a simulation in the Yellow Sea and Bohai sea. The model has an open boundary at the south end. The grid has been rotated so we have this open boundary at the east. figure_1.png The horizontal resolution is 1km with 40 vertical layers. And we applied tidal forcing at the open boundar...

Hi Connor, If you are using the gfortran compiler, can you try to edit the Darwin-gfortran.mk under "~/yourdirectory/trunk/Compilers/" at line 51(maybe not exactly) to be: LIBS := -L$(NETCDF_LIBDIR) -lnetcdf -lnetcdff instead of LIBS := -L$(NETCDF_LIBDIR) -lnetcdf I am not sure this will w...
