Green chromatic coordinate

WebCanopy greenness was quantified using the green chromatic coordinate (G cc), which uses red (R), green (G), and blue (B) digital numbers to calculate the ratio of green within the image (G cc ¼ G/(R þ G þ B)). G cc was calculated using the PhenoCam Image Processor V1.0 (available online).11 This software tool allows a
