Impact of changes in UV and visible radiation on the reflective properties of plant photosynthetic surfaces
We investigated how surface reflectance properties and pigment concentrations of Antarctic moss varied over species, sites, icrotopography, and with water content. We found that species had significantly different surface reflectance properties, particularly in the region of the red edge (approximat...
