sustr and svstr Value has not been read

[hpd14thu]

My force file contains sustr and svstr , but when I run it , I find that these two variable has not been read.

I consider that there are some problems in my head file , but I don't know which CPP option I should add into head file.

Here is my head file:

[jcwarner]

you basically have this set:
/* Forcing */
# ifdef WRF_MODEL
...
# else
/*# define BULK_FLUXES/*
# define ANA_SMFLUX
# endif

so you have ana_smflux on. that will look for analytical values and they are most likely set to 0. so you would want to use
#undef ANA_SMFLUX
and then it will look for su/vstr in forcing files.

Thanks a million! I have solved this problem by this way. But there are another new question which I don't understand:

Here is result.out , the error shows in the last few lines :

Thank you for your reply. It is so kind of you!

But I have checked my forcing file , it seems that I have give each fiekd an attribute of x and y.

Here is my forcing.m ,which used to generate netcdf file:

Your model grid doesn't appear to have lat,lon values in it. The gridded forcing does have them, though one might question your latitude values. Are you sure you didn't swap lat and lon?

[fdaryabor]

Dear,
As stated by Katherine and John, such errors (GET_2DFLD - error while reading variable: or GET_3DFLD - error while reading variable:) are due to the definition of input variables. To avoid encountering such a problem is essential check consistency of the variables in ".nc" file with the list of variables sorted in ".../trunk/ROMS/External/varinfo.dat", even though although want to have an own script I suggest you that have a look at the Matlab toolbox from the ROMS repository. "svn checkout https://www.myroms.org/svn/src/matlab MyDir"

Good luck to you,
Farshid

Thanks a lot! I made some changes, and now there is another problem:

NETCDF_INQ_VAR - requested variable: x

Thanks a million, it's really so kind of you!
According to the BUG :GET_2DFLD - error while reading variable: sustr at TIME index = 1 ,
I have checked my sustr value in forcing file carefully, but I didn't find anything abnormal.
I don't know if there is anything wrong with the time value.( I'm not clear about the time value yet)
Here is my forcing file, if possible, could you please see if there is anything wrong in my forcing file? I really thank you for your self-giving help !

[fdaryabor]

Dear,
Your attached file is completely wrong and it's not really readable for the ROMS, such attributions, dimensions and time format. I suggest you that follow directory ".../trunk/Data/ROMS/CDL" it can help you to find your questions . Good luck to you

Thanks a lot! I'm a beginner at computer programming. According to your suggestion, I found the frc_uvstress.cdl file in ".../trunk/Data/ROMS/CDL" which you recommend, and I transfered it into netcdf file. Then I use a matlab file(which named str_cdl_nc.m) to write values into the ncfile
.

But when I check the forcing.nc file. The value of sms time is very strange, and the dimension of it is incorrect.( I just want to calculate in 2 days since 0:00:00 0)

So I wonder if there is anything wrong in my matlab file(which used to write value into ncfile) ? Thank you so much!

[fdaryabor]

Dear,

Alright, use the following linux commands to convert nc2cdl.

ncdump -b c myfile.nc > myfile.cdl

by the command "vim" or "gedit" (recommended for you to see as .txt file for edit) open myfile.cdl;

gedit myfile.cdl

and also open "frcfile.cdl" from ../trunk/Data/ROMS/CDL;

gedit frcfile.cdl

copy and paste "attributes, dimension, variables definition" from "frcfile.cdl" in "myfile.cdl", then convert "myfile.cdl" to ".nc" file as follow;

ncgen -b myfile.cdl > myfile.nc

Now you try new ".nc" file and see how is work.

Good luck,
