I am using in-situ measured albedo and a new satellite remote-sensed microwave emissivity difference vegetation index (EDVI) to indicate vegetation water content (VWC). I am looking for any existing physical models or numerical models for the leave to calculate the effects of multiple confounding effects on albedo and to simulate the response of albedo to chlorophyll (Ch) and VWC.
Albedo = F (Ch， VWC, ) Any existing model?
Physical-based albedo model for leave?

There are several existing physical models for simulating albedo, such as the PROSPECT-4 model, the BRDF-based BRDF model, and the DISORT model. The PROSPECT-4 model is a four-parameter model for simulating leaf optical properties and albedo, and it has been used to simulate the effect of chlorophyll and VWC on albedo. The BRDF-based BRDF model is a three-parameter model for simulating leaf albedo, and it has been used to simulate the effects of leaf angle distribution and leaf area index on albedo. The DISORT model is a five-parameter model for simulating albedo and diffuse reflectance, and it has been used to simulate the effects of leaf angle distribution and leaf area index on albedo.
If you want to simulate albedo from 400-2500nm under different chlorophyll. Maybe you can have a look at LESS model (http://lessrt.org/), it is a 3D radiative transfer model which can simulate BRDF and albedo under complex vegetation canopies. LESS has integrated a PROSPECT model, with which you can input leaf-level chlorophyll. Therefore, you can input leaf chlorophyll and obtain canopy reflectance and albedo.
