WebIn this method, you should convert your regular coordinate to rotated coordinate and then find the Grid Numbers in rlat/rlon. This tool can convert non-rotated coordinate to rotated coordinate and vice versa. The pivot of rotations is based on CORDEX domains (or you can change it). For extracting data from CORDEX netcdf files, you should ... WebThe parameters Nx, Ny, lat_ll and lon_ll are as before. delta_lat and delta_lon are the latitude and longitude increments of the grid-i.e., the change in latitude or longitude between one grid point and an adjacent grid point.

WebThe projection argument is used when creating plots and determines the projection of the resulting plot (i.e. what the plot looks like). The transform argument to plotting functions tells Cartopy what coordinate system your data are defined in. First we’ll create some dummy data defined on a regular latitude/longitude grid: Let’s try making ...
