Re: error while reading variable: wind_time at TIME index

I used the old executable file OCEANG which was compiled by using the old ROMS codes before, it works.

Re: LtracerSrc LuvSrc can make a problem " insufficient virt

Roms can run sucessfully when I do not turn on "LuvSrc " and "LtracerSrc ". But I got a error "insufficient virtual memory" when I set "LuvSrc " and "LtracerSrc " were ture. You probably have something misconfigured in your river source file, so you should check that it follows the correct netcdf t...

Re: forrtl: severe (41): insufficient virtual memory

insufficient virtual memory The problem is that you don't have enough memory to run the domain you specify in the ocean.in file. What did you set Lm, Mm and N to? How about the number of tracers? Any idea how much memory you have on your system? thanks a lot for ur reply. Lm == 199 ! Number of I-di...

Re: boundary for biogeochemical-ecological modeling

Hi. In my experience, a blow-up like this usually results from a physical circulation problem and not from the ecosystem model. Have you configured this model without the biogeochemistry and ensured that it runs? Also, with only 327 time-steps until a problem, you may be able to output the model ev...

boundary for biogeochemical-ecological modeling

Hi, i am runing npzd. In my study area,alkalinity,NH4,LdetritusN,SDeN,LdetritusC,TIC data is absent. I can not find any other reanalysis data or simulation data from internet. So,I used a constent value for all grids and used as my boundary condition. the same value for all time series (12 months). ...

Re: Problems with npzd_Powell

Thank you very much for the replies Kate and Wilkin. Kate, there is no land mask on the biological initial fields, I'm working on this. Wilkin, I don't know why this is happening. I used to run my experiments in another machine, using MPI, and the minimum grid-spacing was fine. Now, im using OpenMP...

Your surface heat flux looks bizarre to the south there. 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). I go back to check the forcing file (ro...

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 times...

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. Thank you so much for your reply. the information is:...

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?

These data have been computed by a coupled NEMO-PISCES global model) to compute the initial and boundary conditions of NO3 and O2.T...
