Every month, NASA Earth Observatory will offer up a puzzling satellite image here on Earth Matters. The second puzzler is above. Your challenge is to use the comments section below to tell us what part of the world we’re looking at, when the image was acquired, and what’s happening in the scene. Bonus points if […]

We publish a lot of wildfire imagery on our natural hazards page (particularly after the wildfire season ramped up recently in Colorado and other states in the western U.S.) Most of the imagery is acquired during the day by instruments on polar-orbiting satellites: the Moderate Resolution Imaging Spectroradiometer (MODIS) on Aqua and Terra, the Advanced Land […]
To many people, the Arctic is an almost unimaginably remote area at the end of the Earth – more a land of fable and fantasy than a real part of the everyday world. Most people have very little day-to-day connection with the forests, the fields, and the people who are all part of the vast […]
Dr. Jon Ranson is an earth scientist specializing in radar and lidar remote sensing of forests. He uses these tools for studying vegetation type and biomass in ecosystem research at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. He also serves as the Chief of Goddard’s Biospheric Science Laboratory, which is advancing the use of […]
Grant Wiseman Agriculture and Agri-Food Canada Another hot and dry week here in southern Manitoba has us missing the rain just a little bit. We have experienced a very nice dry down cycle in weeks 3 and 4 after a wet up period initially in weeks 1 and 2. By all accounts this will contribute […]
Narendra Das Jet Propulsion Laboratory I am signing off from SMAPVEX12 at Winnipeg with good vibes, pleasant memories and expectation that this will be a very successful campaign. I hope that, like me, most of my teammates have learnt substantially about the study area and had a great field sampling experience, and have also made […]
On June 29, 2012, a long-lived, fast-moving windstorm blew over the eastern United States. The storm started in northwestern Indiana and, over the next 10 hours, traveled roughly 600 miles (1,000 kilometers) toward the East Coast. Wind speeds matched those of an EF-1 tornado in places. The storm uprooted trees, damaged homes, smashed cars, downed […]
A new video series from the National Research Council summarizes what scientists have learned about global warming and climate change. It’s difficult to pack decades of complex research into short video snippets, but the makers of these videos have done an excellent job. As you watch, keep an eye out for mentions of the key […]
