The Shishaldin Volcano on the eastern edge of Alaska's Aleutian Island chain erupted with activity in January of 2020. The eruption on the island of Unimak sent an ash cloud nearly 5 miles into the sky on January 7th, sparking ash alerts for aviators, mariners, and residents of nearby communities. Landsat 8 captured both day and night imagery of the event as it happened.

It's winter in the northern hemisphere, but in Antarctica, summer has just begun. At Zucchelli Station the summer solstice occurred on December 22nd, 2019 at 5:19pm local time. The high temperature that day was a balmy 34 degrees Fahrenheit. These images from Landsat 8 show the distinct difference in sun angles cause by the change in seasons. The September image is from

The LP DAAC recently released a new website designed to help you find the right data for your project. This video walks through 3 search options. https://lpdaac.usgs.gov

The smell of a fresh cut Christmas tree can evoke visions of majestic evergreen forests teeming with winter wildlife. In truth, more than half of U.S. Christmas trees come from farms in Oregon, North Carolina, or Michigan. Cut Christmas Trees area commodity, tracked by the U.S. Department of Agriculture just like corn or soybeans. These USDA aerial images show tree harvest

Scientists at EROS have spent years refining their approach to mapping burn severity using remotely-sensed data from satellites like Landsat, but Landsat comes with limitations. Landsat data cannot see the vegetation below a thick tree canopy, for example. In this episode, we learn about a project in South Dakota’s Black Hills that seeks to leverage 3D data gathered using

It's winter in the northern hemisphere, but in Antarctica, summer has just begun. At Zucchelli Station the summer solstice occurred on December 22nd, 2019 at 5:19pm local time.

Fires burned across California in late 2019. Fall is the state's most dangerous season for wildfires, propelled by dry and windy conditions. In recent years however, the fall fire season has been starting earlier and ending later. A series of images from the MODIS sensor on NASA's Terra and Aqua satellites show the Kincade Fire in northern California. This fire started on

The USGS has developed Landsat-derived Level 2 and Level 3 science products that reduce the amount of time users spend on data processing and provide research quality, applications-ready information to monitor, assess and project how changes in the Earth's surface may affect communities and ecosystems. The Landsat Program is a series of Earth-observing satellites co-

Wildfires burned across Lebanon in mid-October, 2019. A pair of images taken just ten days apart by the European Space Agency's Sentinel-2A satellite show the burn scar from one of the larger wildfires. North of the fire scar is the country's capital, Beirut. The October 18th image reveals several bright spots on the city's streets from numerous fires of a different type.

Each fall, EROS invites its staff scientists and area graduate students to visit for a noontime poster session. The poster sessions offer a change for those researchers to present their results to their peers and get feedback from their fellow scientists. For this episode, we’ll hear about research into biofuels, cloud-friendly Landsat data, shrubland mapping and satellite
