Description
The Carotenoid Reflectance Index 700 (CRI700) is an alternative formulation to CRI550 that uses the 700nm band instead of 550nm to minimize chlorophyll effects. This index provides better performance in leaves with high chlorophyll content and is particularly useful for mature vegetation.
