isofit.inversion.inverse_simple

heuristic_atmosphere(RT, instrument, x_RT, x_instrument, meas, geom)

From a given radiance, estimate atmospheric state with band ratios. Used to initialize gradient descent inversions.

invert_algebraic(surface, RT, instrument, x_surface, x_RT, x_instrument, meas, geom)

Inverts radiance algebraically using Lambertian assumptions to get a reflectance.

invert_simple(forward, meas, geom)

Find an initial guess at the state vector. This currently uses traditional (non-iterative, heuristic) atmospheric correction.
