Lat_u in ROMs output

Hi all, I have recently downloaded a ROMs output from the Golf of Maine Operational Forecast System. I want to extract the U and V parameter from the NetCDF file. Unfortunately, all lat_u values are set to zero. I was wondering if there is any steps to fix it base on the mesh or other variables? Tha...

Re: Time type in nc file

I extracted the zeta variable to compare to the published tidal constituents from NOAA stations in the Gulf of Maine. The amplitude and phase from the model output are very different from the NOAA ones. I picked one of the NOAA stations position and found the closest node from the model to that posi...

Time type in nc file

Hi
Could you please let me know what is the type of time for running the ROMs in the nc output file?
I mean, is it local or GMT?
Thank you

Re: Extracting temperature

Hi Kate. I use this Matlab code to find the nearest node to my location. After using the i, j indices in the lat_rho and lon_rho, it gives me a location very far from my desired location. Could you help me with this? Thank you. yi =43.89818240; xi =-66.31989730; dist = sqrt( (lat_rho-yi)^2 +(lon_rho...

Re: Extracting temperature

yes. This is the index. I will do that.
Does the grid file comes with the NC output?
Thank you

Re: Extracting temperature

I extracted the closest location to my desired latitude and longitude from the 'lon_rho' and 'lat_rho' with the dimension of (xi_rho,eta_rho),in my case the dimensions are as follow: lon_rho(119*119), lat_rho(119*119), and temp(119*119*30*24) and the closest longitude index is 3304 and the correspon...

Re: Extracting temperature

I have the nc file output of ROMs from NOAA Operational Model in the Gulf of Maine. I just need to extract 20 locations from the output. The problem is I have latitude and longitude positions and the temperature dimension in the nc file is different. How I can relate lat and lon to XI and eta?

Extracting temperature

Hi all.
I am totally new with ROMs.I need to extract temp for a specific location with lat and lon coordinate.I checked the nc file output,however the dimension for temp was XI×eta*s_rho_ocean_time.Would you please how I can extract the data?
Thank you
