pyhelios.LeafOptics.LeafOpticsProperties Class Reference

Data class for PROSPECT leaf optical model parameters. More...

Detailed Description

Data class for PROSPECT leaf optical model parameters.

These parameters define the physical and biochemical properties of a leaf that determine its spectral reflectance and transmittance.

       per-leaf Phi_F at SIF emission time (radiation plugin only). Ignored by
       PROSPECT. Default 1.0.

Note

• If protein > 0 OR carbonconstituents > 0, the model uses PROSPECT-PRO mode which ignores drymass and uses protein + carbonconstituents instead.
• Otherwise, the model uses PROSPECT-D mode which uses drymass.
• V2Z and fqe are inert unless the radiation plugin's SIF camera is in use.

from_list()

'LeafOpticsProperties' pyhelios.LeafOptics.LeafOpticsProperties.from_list	(		cls,
		List[float]	values )

Create LeafOpticsProperties from a list of values.

   Accepts the legacy 9-float layout (without V2Z/fqe) for backward
   compatibility with serialized data; missing fields fall back to
   defaults and a ``DeprecationWarning`` is emitted so callers can
   migrate to the 11-element layout.
