prospect5: PROSPECT model version 5 and 5B
In ccrtm: Coupled Chain Radiative Transfer Models

Description Usage Arguments Value References

The PROSPECT5(b) leaf reflectance model. The model was implemented based on Jacquemoud and Ustin (2019), and is further described in detail in Feret et al (2008). PROSPECT models use the plate models developed in Allen (1969) and Stokes (1862). Set Cbrown to 0 for prospect version 5.

1	prospect5(param)

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] = brown pigments content in arbitrary units (Cbrown)
[5] = equivalent water thickness in g/cm2 (Cw)
[6] = leaf dry matter content in g/cm2 - lma - (Cm)

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

[1] = leaf reflectance (rho)
[2] = leaf transmission (tau)
