FASTEM sea surface microwave emissivity parametrization.
This method allows to use FASTEM in retrievals requiring the Jacobian. Otherwise as
surfaceFastem()
. See *SurfaceBlackbody for general remarks about methods of SurfaceSomething type.This is an example on a surface method starting with a capital S, e.g. SurfaceSomething. These methods differ from the methods named as surfaceSomething in two ways:
The surface properties to apply are taken directly from
surface_props_data
.The Jacobian with respect to the surface properties can be obtained.
The Jacobian can be obtained for all variables in
surface_props_data
that the method of concern is using.- For this method,
surface_props_data
must contain these data: “Water skin temperature” “Wind speed” “Wind direction” “Salinity”
