High-resolution satellite images that captured multispectral data recorded the reflections of light from plant leaves. These data are not only of great research importance, providing valuable insights into the physical and biochemical properties of vegetation, but also showcase stunning patterns.

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.
