Description

  • Renamed script x_etopo5.m to x_etopo.m in the matlab/bathymetry directory of the repository. This script can be used to extract any resolution ETOPO bathymetry with the following structure:
    netcdf etopo5 {
    dimensions:
            lon = 4320 ;
            lat = 2161 ;
    variables:
            float topo_lon(lon) ;
                    topo_lon:long_name = "ETOPO5 longitude" ;
                    topo_lon:units = "degrees_east" ;
            float topo_lat(lat) ;
                    topo_lat:long_name = "ETOPO5 latitude" ;
                    topo_lat:units = "degrees_north" ;
            short topo(lat, lon) ;
                    topo:long_name = "Earth surface topography" ;
                    topo:units = "meters" ;
                    topo:comment = "elevation:positive, bathymetry:negative" ;
    
    // global attributes:
                    :title = "ETOPO5 Earth Surface Topography Data Set" ;
                    :comment = "five_minute resolution" ;
                    :name = "etopo5.nc" ;
    
    or
    
    netcdf etopo2 {
    dimensions:
            lon = 10800 ;
            lat = 5400 ;
    variables:
            float topo_lon(lon) ;
                    topo_lon:long_name = "ETOPO2 longitude" ;
                    topo_lon:units = "degrees_east" ;
            float topo_lat(lat) ;
                    topo_lat:long_name = "ETOPO2 latitude" ;
                    topo_lat:units = "degrees_north" ;
            float topo(lat, lon) ;
                    topo:long_name = "Earth surface topography" ;
                    topo:units = "meters" ;
                    topo:comment = "elevation:positive, bathymetry:negative" ;
    
    // global attributes:
                    :title = "ETOPO2 v2 Earth Surface Topography Data Set" ;
                    :comment = "two_minute resolution" ;
                    :name = "etopo2.nc" ;
    
  • Added get_bath.m to extract bathymetry from a NetCDF as a function. It is similar to extract_bath.m driver but in function format. For example,
      [lon,lat,h]=get_bath(Llon,Rlon,Blat,Tlat,OutFile,InpFile)
