sasktran2.constituent.ExtinctionScatterer2D

class sasktran2.constituent.ExtinctionScatterer2D(optical_property: OpticalProperty, extinction_per_m: ndarray, extinction_wavelength_nm: float, **kwargs)

Bases: NumberDensityScatterer2D

A Geometry2D scatterer normalized to an extinction profile.

This is the native-grid counterpart to ExtinctionScatterer. The supplied extinction is converted to number density using the optical property’s cross section at extinction_wavelength_nm. The conversion is evaluated independently at every Geometry2D location, including the supplied optical property arguments.

Parameters:

• optical_property (OpticalProperty) – Property supplying extinction, scattering, and phase-function data.

• extinction_per_m (numpy.ndarray) – Extinction in m^-1 with shape (horizontal, altitude).

• extinction_wavelength_nm (float) – Wavelength in nanometres at which extinction_per_m is specified.

• **kwargs – Additional optical-property inputs. Shape rules are identical to NumberDensityScatterer2D.

__init__(optical_property: OpticalProperty, extinction_per_m: ndarray, extinction_wavelength_nm: float, **kwargs) → None
