The combined PROSPECT leaf optical properties model and SAIL canopy bidirectional reflectance model, also referred to as PROSAIL, has been used for about sixteen years to study plant canopy spectral and directional reflectance in the solar domain. PROSAIL has also been used to develop new methods for retrieval of vegetation biophysical properties. It links the spectral variation of canopy reflectance, which is mainly related to leaf biochemical contents
, with its directional variation, which is primarily related to canopy architecture and soil/vegetation contrast. This link is key to simultaneous estimation of canopy biophysical/structural variables for applications in agriculture, plant physiology, and ecology at different scales. PROSAIL has become one of the most popular radiative transfer tools due to its ease of use, general robustness, and consistent validation by lab/field/space experiments over the years.


PROSPECT
Outline: Below one can find four compressed files corresponding to the versions 4 and 5 of the PROSPECT model, both in Fortran 90 and Matlab 7. All versions allow to calculate leaf optical properties in the solar domain between 400 nm and 2500 nm (1 nm step). The input variables are the chlorophyll concentration (Cab), the carotenoid concentration (Ccx) [only in PROSPECT-5], the equivalent water thickness (Cw), the dry matter content (Cdm) content, and the leaf structure parameter (N). The output variables are the leaf directional-hemispherical reflectance and transmittance. The files "dataSpec_P4" and "dataSpec_P5" contains the specific absorption coefficients of each constituent and the refractive index of leaf material. The specific absorption coefficient corresponding to brown pigment (Cbp) is provided by Frédéric Baret (EMMAH, INRA Avignon, baret@avignon.inra.fr) and used with his autorization.

SAIL
Outine: Below one can find a WinZip file containing all the 4SAIL codes plus a sample application program called SAILVTIR that demonstrates the calculation of vegetation cover, emissivity, reflectance, radiance and brightness temperature as a function of LAI. A sample input and output file can be found in the "Release" folder. The output file has been edited to make it better readable. The software has been developed with Visual Fortran.
