the parameter in the avg nc file is empty
Hi, everyone, I run ROMS and got the empty results (the NaN was shown in the first step and was attached below). I used Woapisces (have been provided by Olivier Aumont. These data have been computed by a coupled NEMOPISCES global model) to compute the initial and boundary conditions of NO3 and O2.Then, I used WOA2009 ( World Ocean Atlas directory 2009 )to compute the initial and boundary conditions of temperature and salty. Then, I used coads dataset to compute forcing and boundary condition of Wind stress, Heat fluxes w3, Fresh water fluxes (evaporation  precipitation), Sea surface temperature and heat flux sensitivity to the sea surface temperature (dQdSST),Sea surface salinity,Short wave radiation, pair air pressure. the chlorophyll initial conditions was computed by using modis data in 2016,and NH4, LdetritusN, and et al were set as a constant with the time and loction in the boundary files. finally, i got a empty result and showd as below. Is there any way I can figure out what is the problem? the grid files? the water depth problem? or the parameter in the forcing file , boundary file ,and initial file are not match? or show i check some scripts to find out it?
Thank you so much for your help in advance. I have long struggled with the problem

Re: the parameter in the avg nc file is empty
for Sea surface temperature and salinity in forcing files were computed by using the coads dataset (coads05) ,but the salinity and temperature in the boundary files were computed by using woapisces dataset. Would that be a problem?
Re: the parameter in the avg nc file is empty
Perhaps you should show us the ROMS output where it is reading all these files. It gives the min and max of everything, so that we can see if they are all sensible.
If you are getting NaNs, that's from the model physics, not the ecosystem stuff.

Re: the parameter in the avg nc file is empty
You had said you were applying the stresses from COADS, but yet the model is reading winds, air pressure and the rest. This looks odd:
in that all the winds are negative. I would ask the model to write out surface fluxes and stresses to see if those look reasonable. I would try a much shorter timestep to see if you can get it to run long enough to output some useful fields so you can figure out where in the domain it is going bad.
I would not worry about starting from rest. The model spins up to match the density fields pretty quickly.

thx,I really appreciated the suggestions you gave. it is important clue for me who only have biological background.kate wrote:You had said you were applying the stresses from COADS, but yet the model is reading winds, air pressure and the rest. This looks odd:

I changed the timestep.

the parameter only at first time step existed in the avg.nc file. I attached the nc file here.
I will try to turnoff the biological mode part and check the forcing, grid files again.

Your surface heat flux looks bizarre to the south there.

Re: the parameter in the avg nc file is empty
i did my best to figure out why latent,sensible,and shlux is so wield in history file "roms_his.nc" (results were attached below). however, I have no clue. "lwrad" seems ok in history file(roms_his.nc).kate wrote:Your surface heat flux looks bizarre to the south there.
I go back to check the forcing file (roms_frc.nc) which I used "coads" and "NCEP/NCAR Reanalysis Monthly Means" data (attached below).

Re: the parameter in the avg nc file is empty
parameters in restart file"rst.nc" look normal.
paramters in bry.nc "boundary condition files" look normal except NH4 is a constant .
it is only one effective value in my region (the region is too small), and this value was obtained from coads data. acutally, i set the value of TIC,alkalinity by myself. NO3 which from coads data was multiplied by a different factor to get TIC,alkalinity, and so on.
