Relation of Chlorophyll Fluorescence Sensitive Reflectance Ratios to Carbon Flux Measurements of Montanne Grassland and Norway Spruce Forest Ecosystems in the Temperate Zone
Figure 1
The image shows a true color red, green, and blue (RGB) composition of a Spruce forest measured in the Beskids Mountains acquired on 2nd September of 2005 at 10:00 A.M. (a) The same image was converted into the reflectance ratio R686/R630 where the pixels in the shadow and with nongreen vegetation are excluded from the image and further analysis (b).
