NASA’s PACE satellite can measure subtle changes in leaf color by detecting pigments like chlorophyll, carotenoids, and anthocyanins. Together, these pigments can help scientists assess how healthy the plants are! This visualization shows a full year of vegetation data from March 2024 to March 2025. Magenta represents anthocyanins, green represents chlorophyll, and cyan represents carotenoids. The brighter the colors are, the more leaves are in that area. White represents areas where all three pigments were roughly equal. Watch how the colors change and move. This illustrates how vegetation changes throughout the seasons and how plants adapt to stresses like weather fluctuations.
