| Summary : Silhouette to Area Ratio of Tilted Surfaces
|
Description :
Implementation of trigonometric functions to calculate the exposure of
flat, tilted surfaces, such as leaves and slopes, to direct solar
radiation. It implements the equations in A.G. Escribano-Rocafort, A.
Ventre-Lespiaucq, C. Granado-Yela, et al. (2014)
< doi:10.1111/2041-210X.12141> in a few user-friendly R functions. All
functions handle data obtained with \'Ahmes\' 1.0 for Android, as well as
more traditional data sources (compass, protractor, inclinometer). The
main function (star()) calculates the potential exposure of flat,
tilted surfaces to direct solar radiation (silhouette to area ratio,
STAR). It is equivalent to the ratio of the leaf projected area to
total leaf area, but instead of using area data it uses spatial
position angles, such as pitch, roll and course, and information on the
geographical coordinates, hour, and date. The package includes
additional functions to recalculate STAR with custom settings of
location and time, to calculate the tilt angle of a surface, and the
minimum angle between two non-orthogonal planes.
