NASA's PACE satellite image could help us to evaluate plant health

The following information is from NASA's post on FB today (https://www.facebook.com/share/v/14EdB9bGkUQ/)

This is a year’s worth of PACE vegetation data.
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.

以下這段話是翻譯自NASA的FB貼文：

這是一年的NASA的 PACE 植被資料。

NASA 的 PACE 衛星可以透過檢測葉綠素( chlorophyll)、類胡蘿蔔素(carotenoids)和花青素(anthocyanins)等色素來測量葉片顏色的細微變化，這些色素可以幫助科學家評估植物的健康狀況！

此視覺化圖表展示了 2024 年 3 月至 2025 年 3 月全年的植被數據。洋紅色代表花青素，綠色代表葉綠素，青色代表類胡蘿蔔素。顏色越亮，該區域的葉子越多。白色代表三種色素含量大致相等的區域。

觀察顏色如何變化和移動。這顯示了植被在整個季節中如何變化，以及植物如何適應天氣波動等壓力。
