Above the Earth, Below the Surface: Landsat’s Role in Monitoring Water Quality
The Landsat Program is a series of Earth-observing satellite missions jointly managed by NASA and the U.S. Geological Survey. The NASA/USGS program provides the longest continuous space-based record of our world. The data/images it supplies have impacted millions of people worldwide. NASA Goddard shared this video on Youtube!
Only 3% of water on Earth’s surface is fresh – a vital resource for electricity, farming, and life. As global temperatures rise, disruptions like algal blooms, glacial melt, and drought threaten our aquatic ecosystems. Safeguarding these resources is crucial, and while scientists use a variety of ground-based techniques to gauge water quality, the Landsat program has provided water quality data from orbit for decades. Here are just a few ways Landsat satellites lend us a hand when it comes to monitoring water quality.
