class sasktran2.constituent.SurfaceThermalEmission(temperature_k: float, emissivity: ndarray)[source]#

Bases: Constituent

A thermally emissive surface that is defined by a temperature and emissivity. The emission is calculated as the product of emissivity and the Planck function.

This can either operate in a “scalar” mode where the emissivity is constant in wavelength, or a “native” mode where the emissivity is defined on the same grid as the atmosphere.

Parameters:

  • temperature_k (float) – Surface temperature.

  • emissivity (np.ndarray) – Surface emissivity. Can be a scalar to indicate it is constant in wavelength. If set to an array it must match the atmosphere wavelength grid dimenstion.
