由衞星衍生的光譜數據,記錄了植物葉片反射光譜的詳細資訊。這些資料不僅具有重要的研究價值,同時展現出美麗的圖案。圖片擷取自《環境遙感》《Remote Sensing of Environment》(2024),

Through the Cosmic Lens: Observing Plants from Space’s Eye! Researchers led by Professor Jin WU from HKU School of Biological Sciences have made a breakthrough in mapping plant traits from space using satellite data.
Using time-series satellite data, they have developed an innovative method to map plant traits from space. By analyzing reflections of light from plant leaves and observing plant life cycles, they have gained valuable insights into ecosystem functioning and resilience. This innovative approach has the potential to enhance our understanding of climate change impacts and ecosystem health.
