I have a NetCDF data for surface wind speed and surface current for different time-steps (about 10 years) of a particular area. I converted the Netcdf data into different raster layers and eventually edited it. Now I need to couple it back to NetCDF but I can only couple for 1 variable (surface wind). The challenge is to couple for both variables in 1 netcdf file. How do I couple for the 2 variables (Surface wind and surface current) in 1 Netcdf file.
