Simulations of below-canopy solar radiation 
at the 
Wind River Canopy Crane Research Facility

Scott N. Martens
 
Introduction and Simulations with CrnSol
Some background info on the simulations and results for first simulations with CrnSol; includes a map of tree locations.
The Digital Elevation Model for the Crane Site
Shows the details of the DEM constructed for the crane site: elevation, slope, aspect.  Includes a plot of tree locations.
Simulation results of below-canopy PAR from SolTran 
Includes a description of the SolTrans model, its parameterization, and results.  View animations of the daily and yearly time-courses of transmitted direct PAR at the site. View an animation of a vertical transect of fisheye views.
Comparison of modeled vs measured below-canopy PAR 
Includes a map of the locations of the points measured, a plot of the daily time course of PAR at those points and in the open, and simulated time courses of PAR at each point.
