Summary:
- NASA scientists have developed a new method to map plant productivity on land using data from an ocean satellite.
- The satellite measures the amount of chlorophyll in the ocean, which is an indicator of phytoplankton growth. The scientists found that this data can also be used to track the growth of plants on land.
- This new technique allows scientists to monitor the health and productivity of vegetation across the globe, which is important for understanding the Earth's carbon cycle and the impact of climate change on ecosystems.
