% read the annual mean data as an example ncid=netcdf.open(‘annual_isopycnal.nc’,’nowrite’); % get the longitude data lon_id=netcdf.inqVarID(ncid,’lon’); lon=netcdf.getVar(ncid,lon_id); % get the latitude data lat_id=netcdf.inqVarID(ncid,’lat’); lat=netcdf.getVar(ncid,lat_id); % get the sigma_level data s s_id=netcdf.inqVarID(ncid,’sigma_level’); s=netcdf.getVar(ncid,s_id); % get the zonal and meridional absolute geostrophic velocity data u_id=netcdf.inqVarID(ncid,’u’); v_id=netcdf.inqVarID(ncid,’v’); % get the unit units=netcdf.getAtt(ncid,u_id,’units’); % get the isopycnal level depth data d_id=netcdf.inqVarID(ncid,’sigma_depth’); % get the unit units=netcdf.getAtt(ncid,d_id,’units’); % get al.l the data u=netcdf.getVar(ncid,u_id); v=netcdf.getVar(ncid,v_id); d =netcdf.getVar(ncid,d_id); % get part of the data % example: isopycnal level ‘k’ data u=netcdf.getVar(ncid,u_id,[0,0,k-1,0],[344,720,1,1]); v=netcdf.getVar(ncid,v_id,[0,0,k-1,0],[344,720,1,1]); d=netcdf.getVar(ncid,d_id,[0,0,k-1,0],[344,720,1,1]); % set the garbage data to NaN. u(u>1e30)=NaN; v(v>1e30)=NaN; % close the data file netcdf.close(ncid);
