class RadiativeTransferUnknownsConfig(sub_configdic=None)

Bases: BaseConfigSection

Radiative transfer unknowns configuration.

class RadiativeTransferConfig(sub_configdic=None)

Bases: BaseConfigSection

Forward model configuration.

interpolator_style

Style of interpolation. - mlg = Multilinear Grid - rg = RegularGrid Speed performance:

mlg >> stacked rg >> unstacked rg

Caching provides significant gains for rg, marginal for mlg

Type:

str

overwrite_interpolator

Overwrite any existing interpolator pickles

Type:

bool

cache_size

Size of the cache to store interpolation lookups. Defaults to 16 which provides the most significant gains. Setting higher may provide marginal gains.
