Every weather forecast begins long before an icon appears on your phone. Behind each prediction lies a vast global system of satellites, sensors, data centers, supercomputers, and decades of scientific research working together to observe our living planet.
In this episode of the ALLATRA Podcast in collaboration with ALLATRA Global Research Center, Dr. Stephen M. Volz shares insights from decades of leadership in NASA and NOAA. As former Associate Director of NASA's Earth Science Flight Program and former Assistant Administrator of NOAA's National Environmental Satellite, Data, and Information Service (NESDIS), he helped build and oversee the systems that monitor our planet from space.
Drawing on decades of experience in NASA and NOAA, Dr. Volz explains how humanity has transformed its ability to observe Earth, from studying individual atoms and the origins of the universe to managing constellations of satellites that continuously monitor our planet. He shares why Earth should be understood not as separate oceans, atmosphere, and land, but as one interconnected living system.
The conversation explores how satellite observations become weather forecasts, why climate prediction is far more complex than it seems, how artificial intelligence is reshaping Earth observation, and why human expertise remains irreplaceable. Dr. Volz also discusses the critical role of oceans in Earth's climate system and why understanding our planet is one of humanity's greatest scientific challenges.
In this episode:
• How satellites observe Earth from space
• How weather forecasts are created
• Weather forecasting vs. climate prediction
• The role of oceans in Earth's climate
• AI in Earth observation: opportunities and limits
• Why human expertise still matters
• The future of Earth observation
The podcast is hosted on the ALLATRA platform.
