3 years ago yup after changing lon_rho/lat_rho : lon/lat in roms file & xt_ocean/yt_ocean : lon /lat Progress happened but now the index Error as File "/home/sakib/Desktop/own_download_pyroms/pyroms/examples/Arctic_HYCOM_GLBy/remap_clm.py", line 138, in remap_clm print('before vertical remap 1', dst_varz[:,928,324]) IndexError: index 928 is out of bounds for axis 1 with size 757

3 years ago You've got choices - comment out those print statements or print out a point within your grid.

3 years ago Hi @kshedstrom, Hope you are very well. Here in INDIA situation is very bad due to COVID19. Soon the things will be good in INDIA. Coming to generation of Initial Condition and Boundary Condition. Initial condition Generation is excellent . Many Many Thank you for this. but Boundary Condition I am not getting the values which is required. Such as - 1- Boundary Condition values are correct but it's indexing system is wrong . showing the data in j index value instead of k. 2- Boundary Condition only showing one time stamp instead of 30 days timestamps(whole one month i am running).

3 years ago My Boundary condition show data
I think my file should be k=1:40 and L-index will be L=1:31(for jan month)
let me know where i am making mistake
Any Help will be Appreciable.
Thank you.

3 years ago I've heard things are bad in India, sorry about that. Things are also not great in Fairbanks, with the hospital full of angry, younger, unvaccinated people - when vaccines are available for all. People are acting unwisely in bars and some churches.
When I was making boundary files from HYCOM, the HYCOM variables are in one file per day. I loop over all the files and then concatenate the outputs into one file. If all your records are in one file, you have to loop over all the times in that file. The file you show is going to run on four processes and it wants to split it up by files - you'll have to rewrite that logic. The easy thing is to make it serial, strip out the multiprocessing.
The boundary file should look something like:
netcdf HYCOM_GLBy_2019_bdry {
dimensions:
s_rho = 50 ;
s_w = 51 ;
eta_rho = 1090 ;
xi_rho = 690 ;
ocean_time = UNLIMITED ; // (349 currently)
eta_u = 1090 ;
xi_u = 689 ;
eta_v = 1089 ;
xi_v = 690 ;
eta_psi = 1089 ;
xi_psi = 689 ;
variables:
double theta_s ;
theta_s:long_name = "S-coordinate surface control parameter" ;
:
double ocean_time(ocean_time) ;
ocean_time:long_name = "time" ;
ocean_time:units = "days since 1900-01-01 00:00:00" ;
ocean_time:field = " " ;
double zeta_north(ocean_time, xi_rho) ;
zeta_north:_FillValue = -30000. ;
zeta_north:long_name = "free-surface north boundary condition" ;
zeta_north:units = "meter" ;
zeta_north:field = "zeta_north, scalar, series" ;

temp_north:long_name = "potential temperature north boundary condition" ;
temp_north:units = "Celsius" ;
temp_north:field = "temp_north, scalar, series" ;
double temp_south(ocean_time, s_rho, xi_rho) ;
temp_south:_FillValue = -30000. ;
temp_south:long_name = "potential temperature south boundary condition" ;
temp_south:units = "Celsius" ;

Coming to creation of boundary condition I am getting Error after changing the remap_bdry.py when second iteration of time loop in remap_bdry.py i am getting Error. Error coming is : -

3 years ago Hi @kshedstrom Hope you everything is fine. I have solved the timestamp problem but still stuck at depth k problem I am getting k depth as null. Can you please guide me how to solve the k depth problem , I should get k 1;40 which i am getting in my final file. please let me know where i have to change the code line. either j value should be shift to k or k i have to create. For reference final month file detail as below:
yes? use month.nc

3 years ago So you are getting 50 depths instead of 40. You tell it how many levels in the gridid.txt file:
id = ARCTIC5
name = ARCTIC5
grdfile = /import/AKWATERS/kshedstrom/gridpak/Arctic5/grid_Arctic_5.nc
N = 50
grdtype = roms
Vtrans = 4
theta_s = 7
theta_b = 2
Tcline = 250 A lot of my examples have N=50. Do you have such a chunk in your gridid.txt?

Thanks for your reply and help.
I am really honor and pleased that i am clearing my doubts and you are so kind kind hearted and helpful person.
I am getting confuse in my j index there is not only 1:50 but some of the places 1:757 as well.
I think k value is not writing itself.
and i have gridid.txt there before it changed N=40 but still same scenario.
I am using previous IC created regrid_t.nc file, is it fine to use the same regrid_tc.nc file in Boundary condition creation.
and i am not able to find the python script where the gridid.txt was read and variable values were assigned from gridid.txt.
can you guide me please what was the python script name where gridid.txt file was read .
is the python script regrid_Glby.py or make_remap_weights_file.py
Any Help will be Appreciable.
Thank you.

3 years ago If you are using xESMF, you do not need to run make_remap_weights_file.py. The file reading gridid.txt is make_bdry_file.py, the line with pyroms.grig.get_ROMS_grid('MYGRID'), where 'MYGRID' points to your grid blob in gridid.txt.
Using the old regrid_t.nc should be fine. It has the lateral remap weights, not the vertical ones.
I have no idea what code you are using to parse your output, but U_NORTH with 1:1080, 1:50 would be fine if you had 50 vertical levels.

Is there any better approch to merge the daily files to montly single file ?

3 years ago Like I said, I have no idea what software you are using to show this. Therefore I can't tell you how to teach it about k.
Using ncrcat is what I do too. I don't know a better way.

3 years ago The file is likely to be fine at this point. Next is to look at it in ncview and/or see if ROMS will happily read it.
