A)high reflectance in the NIR and low reflectance in VIS.
B)low reflectance in the NIR and low reflectance in VIS.
C)high reflectance in the NIR and high reflectance in VIS.
D)low reflectance in the NIR and high reflectance in VIS.

Question

Quizplus · Accepted Answer

NPP is related to the amount of photosynthesis occurring in vegetation, which primarily involves the absorption of visible light and reflection of near-infrared (NIR) light. High reflectance in the NIR and low reflectance in VIS provide an indication of healthy vegetation, which can then be used to estimate NPP through satellite data. Therefore, option A (high reflectance in the NIR and low reflectance in VIS) is the best choice.
