GMS: NASA Satellites See Wildfires from Space

As wildfires burn across California, NASA satellites help gather data about where the fires are and how smoke travels across the state. The smoke from the fires is even visible a million miles away from Earth, captured by NASA's Earth Polychromatic Imaging Camera (EPIC) onboard NOAA's Deep Space Climate Observatory (DSCOVR). The Terra spacecraft can see fires in both daylight and at night, helping aid firefighters in tracking and stopping the blazes. NASA's unique vantage point in spa

GMS: NASA Watches 30 Years of Ozone Success

Thirty years ago, the nations of the world agreed to the landmark ‘Montreal Protocol on Substances that Deplete the Ozone Layer.’ The Protocol limited the release of ozone-depleting chlorofluorocarbons (CFCs) into the atmosphere. Since the 1960s, NASA scientists have worked with NOAA researchers to study the ozone layer, using a combination of satellite, aircraft and balloon measurements of the atmosphere. Things have been improving in the 30 years since the Montreal Protocol. Thanks to

GMS: Following Carbon Dioxide Through the Atmosphere

Carbon dioxide plays a significant role in trapping heat in Earth's atmosphere. The gas is released from human activities like burning fossil fuels, and the concentration of carbon dioxide moves and changes through the seasons. Using observations from NASA's Orbiting Carbon Observatory (OCO-2) satellite, scientists developed a model of the behavior of carbon in the atmosphere from September 1, 2014 to August 31, 2015. Scientists can use models like this one to better understand and predi
