A two-layer canopy reflectance model is developed in the group of vegetation remote sensing at Tartu Observatory. The model is published in Kuusk, A. A two-layer canopy reflectance model, J.Q.S.R.T., 2001, 71(1): 1-9.
NB! The contribution of soil to diffuse fluxes is erroneous in this paper. The errors are fixed in the July 2009 version of the model, and in the manual of the model.
Here you can find the manual of the model:
Version 07.2009
Version 12.2012

The model is coded in Fortran. The same code works both in direct and inverse modes.
The current version of the model is acrmf_12.2012. To get the current version of the model please mail to A. Kuusk, andres@to.ee

The August 2003 version of the model is on the included CD-ROM of Liang, S. Quantitative Remote Sensing of Land Surfaces, Wiley, 2004.

A GUI version of the 2003 version was made by Joel Kuusk. This model works only in direct mode, here you can see screenshots of CR spectrum and angular distribution.
