Ocean Modeling Discussion

Thanks for your promptly reply! Yes, I have checked all the files you referred, and find out that they are the same. The image on the right looks like it is having problems getting open boundary information into the domain. Are you using exactly the same open boundary conditions in the dot-in, and t...

Dear ROMS users, I run my application on different platforms. Since I using the same configurations(cpp, initial, boundary, forcing), I expect the solutions to be the same or at least not far from each other. However, I got two very different solutions. The only difference between the two cases is t...

Thanks for your prompt reply! I may know where the issue occurs. I will have a try.

Dear ROMS users I am running the WC13 case using RBL4DVAR and RPCG options. But the compiling is aborted. The following is the error message: sum_grad.f90(61): error #6460: This is not a field name that is defined in the encompassing structure. [TL_T] & OCEAN(ng) % tl_t, sum_grad.f90(62): error ...

not sure what you mean by the visc values. Are you using horiz viscosity: #define UV_VIS2 #define MIX_S_UV then you can set VISC2 == 2.0d0 ! m2/s ??? or something like that Perhaps the tracer horiz diffusivity is more what you need: # define TS_DIF2 # define MIX_GEO_TS TNU2 == 0.5d0 ! m2/s ??? or s...

Greetings, I have a question about the passive tracer(temp,salt): My model horizontal resolution is 10 km. The distribution of the tracers seems unphysical. I assume it may be due to the visc coefficient. I set the value to 3.0 because i want to give the disturbances more time to fade out. The resul...

Thanks for your prompt reply! Before doing assimilation, I run NLM for 6 years using Lm3CLM=T and LnudgeM3CLM=T. And the same configuration is set in my assimilation procedure.My forcing field is in blk file. I make a mistake in the get_cycle.F, I will change code back. I will delete the cycle_lengt...

Dear users I am running an I4DVAR experiment, and NLM nudged to climatology u,v,temp,and salt field. my cycle_length is 365.25，and the climatology time sequence is (15, 345) with 30 intervels。my assimilation window is from 2015-12-1 to 2015-12-7. When the adjoint model set up the 3d field using set_...

look at the entire output file, there might have been more info before the nan.

Thanks for your efficient reply. I found that there are many nans in my climatology file which is the reason for roms' blowing up. Now it runs well.

I have a similar problem. when i nudging climatology field, including u,v,temp and salt, my model blow up, and my rst file have no valid data, but clim file and nudging coefficent file has been read without errors, i am unable to figure out this problem, Please help me, thank you in advance!
