epygram.fields.gimme_one_point(longitude, latitude, field_args=None, geometry_args=None, vertical_geometry_args=None, geometry_class=<class 'epygram.geometries.UnstructuredGeometry.UnstructuredGeometry'>)

Builds an empty PointField at given (longitude, latitude).

Parameters

• field_args – to be passed to field constructor, e.g. a validity

• geometry_args – to be passed to geometry constructor

• vertical_geometry_args – to be passed to vertical_geometry constructor

• geometry_class – geometry class tu use (default: UnstructuredGeometry)

epygram.fields.make_vector_field(*components)

Creates a new epygram.D3VectorField or subclass from several epygram.D3Field or subclass representing the components of the vector in the field geometry.

epygram.fields.psikhi2uv(psi, khi)

Compute wind (on the grid) as a D3VectorField (or subclass) from streamfunction psi and velocity potential khi.
