sasktran2.constituent.NumberDensityScatterer(...)	A scattering constituent that is defined by a number density on an altitude grid and an optical property
sasktran2.constituent.NumberDensityScatterer2D(...)	A scatterer specified by number density on a Geometry2D grid.
sasktran2.constituent.ExtinctionScatterer(...)	A scattering constituent that is defined by a number density on an altitude grid and an optical property

sasktran2.constituent.MonochromaticVolumeEmissionRate(...)	A monochromatic volume emission rate.
sasktran2.constituent.Manual(extinction, ssa)	An implementation of a manual constituent where the user provides the extinction, single scattering albedo, and optionally the Legendre moments.

BRDFs

sasktran2.constituent.LambertianSurface(albedo)	A Lambertian surface that is defined by albedo at discrete grid points.

Solar Irradiance Models

sasktran2.constituent.SolarIrradiance([...])

A constituent that calculates the solar irradiance at TOA using a reference solar irradiance spectrum.

Emissions

sasktran2.constituent.ThermalEmission()	An implementation of thermal emissions calculated from the Planck function.
sasktran2.constituent.SurfaceThermalEmission(...)	A thermally emissive surface that is defined by a temperature and emissivity.

Dummy Constituents

sasktran2.constituent.AirMassFactor()

A dummy atmospheric constituent that does not add any terms to the atmosphere, but rather enables the calculation of Air Mass Factor derivatives.
