Brightness-Shape-Moisture (BSM) soil reflectance model. BSM simulates the isotropic reflectance for both dry and wet soil.

For dry soil reflectance simulation, the users could find the details on the modelling in Verhoef et al., (2018) or Yang et al., (2020).

For the effects of soil mositure, the users are referred to Yang et al., (2020).
