Netcdf Input

mnetcdf (python) pnetcdf(fortran)

Magics++ is capable of reading NetCDF data files.

From this version, Magics can understand data represented in a projection different than the traditional latlon.The NetCDF header should just contain the proj4 string representing the projection used to describe the data. This is still a very early stage, but contact us if you are interested in such a functionality.

Example of metadata (ncdump):
//Variables

		double x(x) ;

                x:standard_name = "projection_x_coordinate" ;

                x:long_name = "x coordinate of projection" ;

                x:units = "m" ;

        double y(y) ;

                y:standard_name = "projection_y_coordinate" ;

                y:long_name = "y coordinate of projection" ;

                y:units = "m" ;

        float accumulation(duration, y, x) ;

                accumulation:long_name = "observed 24-hour rainfall accumulation" ;

                accumulation:_fillvalue = -9999.f ;

                accumulation:units = "mm" ;

                accumulation:grid_mapping = "lambert_azimuthal_equal_area" ;

// global attributes:

                :datatype = "operaGrid" ;

                :time = "09/01/2017 12:00:00" ;

                :conventions = "CF-1.5" ;

                :projection = "+proj=laea +lat_0=55.0 +lon_0=10.0 +x_0=1950000.0 +y_0=-2100000.0 +units=m +ellps=WGS84" ;

                :grid_corners = -10.4345768386404, 31.7462153193251, -39.5357864125034, 67.0228327583087, 57.8119647501499, 67.6210371027505, 29.421038635578, 31.987650277945 ;
