Surface thermal

source module isofit.surface.surface_thermal

Classes

  • ThermalSurface — A model of the surface based on a Mixture of a hot Black Body and Multicomponent cold surfaces.

source class ThermalSurface(full_config: Config)

Bases : MultiComponentSurface

A model of the surface based on a Mixture of a hot Black Body and Multicomponent cold surfaces.

.

Methods

  • xa — Mean of prior distribution, calculated at state x. We find the covariance in a normalized space (normalizing by z) and then un- normalize the result for the calling function.

  • Sa — Covariance of prior distribution, calculated at state x.

  • fit_params — Given a reflectance estimate, find the surface reflectance

  • dlamb_dsurface — Partial derivative of Lambertian reflectance with respect to state vector, calculated at x_surface.

  • calc_Ls — Emission of surface, as a radiance.

  • dLs_dsurface — Partial derivative of surface emission with respect to state vector, calculated at x_surface.

  • drdn_dsurface — Derivative of radiance with respect to full surface vector

  • summarize — Summary of state vector.
