NRLMSISE00 atmospheric model.

Constructor.

Parameters:

  • input_data_type (NRLMSISE00.InputDataType) -- Input data source type.

  • f107_constant_value (float) -- F10.7 constant value.

  • f107_average_constant_value (float) -- F10.7a constant value.

  • kp_constant_value (float) -- Kp constant value.

  • earth_frame (Frame) -- Earth frame.

  • earth_radius (Length) -- Earth radius [m].

  • earth_flattening (float) -- Earth flattening.

  • sun_celestial (Celestial) -- Sun celestial object. Defaults to None.
