pywgrib2_xr.grid2earth_grid¶
-
pywgrib2_xr.grid2earth_grid(grid)[source]¶ computes Earth coordinates of all the grid points.
- Parameters
grid (Grid) – Grid definition instance.
- Returns
Calculated coordinates: a dictionary with keys {‘crot’, ‘srot’, ‘area’, ‘lat’, ‘lon’, ‘xpts’, ‘ypts’} where:
crot, srot : Cosine and sines of clockwise vector rotation.
area : Area weights in m^2. Proportional to the square of the map factor in the case of conformal projections.
lat, lon : Latitudes and longitudes.
xpts, ypts : Grid point coordinates.
- Return type
