xa(x_surface, geom)

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(x_surface, geom)

Covariance of prior distribution, calculated at state x.

fit_params(rfl_meas, geom, *args)

Given a reflectance estimate, find the surface reflectance

dlamb_dsurface(x_surface, geom)

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

calc_Ls(x_surface, geom)

Emission of surface, as a radiance.

dLs_dsurface(x_surface, geom)

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

drdn_dsurface(rho_dif_dir, drfl_dsurface, dLs_dsurface, s_alb, t_total_up, L_tot, L_down_dir)

Derivative of radiance with respect to full surface vector

summarize(x_surface, geom)

Summary of state vector.
