prospectd {ccrtm}

PROSPECT model version D

Description

The PROSPECTD leaf reflectance model. The model was implemented based on Jacquemoud and Ustin (2019), and is further described in detail in Feret et al (2017). PROSPECT models use the plate models developed in Allen (1969) and Stokes (1862).

Usage

prospectd(param)

Arguments

param

A named vector of PROSPECT parameters (note: program ignores case):

• [1] = leaf structure parameter (N)

• [2] = chlorophyll a+b content in ug/cm2 (Cab)

• [3] = carotenoids content in ug/cm2 (Car)

• [4] = Leaf anthocyanin content (ug/cm2) (Canth)

• [5] = brown pigments content in arbitrary units (Cbrown)

• [6] = equivalent water thickness in g/cm2 (Cw)

• [7] = leaf dry matter content in g/cm2 - lma - (Cm)

Value

spectra matrix with leaf reflectance and transmission for wavelengths 400 to 2500nm:

• [1] = leaf reflectance (rho)

• [2] = leaf transmission (tau)
