Image of the Week - Petermann Glacier 2020 Update

Petermann Glacier in northwestern Greenland is known to generate large icebergs, most notably in 2010 and 2012. Another large iceberg may be forming now. A new rift was spotted on the glacier in 2017. Since then, imagery from both Landsat and Europe's Copernicus Sentinel-2 satellites show the rift lengthening and meeting up with and older crack. The potential iceberg could

Outreach EROS Overview

This is EROS.

It's located just north of Sioux Falls in South Dakota in the United States on the planet Earth!

EROS stands for Earth Resources Observation and Science. It's a federal government facility where over 600 talented women and men work together to capture, store, and study images of the Earth taken from high above. Our Earth is always changing, and

Eyes on Earth Episode 38 – Time Series Analysis with Landsat

In the past, remote sensing scientists looked for change on the Earth’s surface primarily by comparing one Landsat image to another. Today, open access to Landsat data, high-performance and cloud computing capabilities and sophisticated algorithms can be used to scan the entirety of the archive for change, enabling researchers to learn more about how the landscape shifts

Image of the Week - Iowa Fields Flattened

The punishing derecho storm that struck the Midwest in early August had an immediate impact on Iowa's farm fields. But it took weeks for the long term damage to appear in satellite imagery. Landsat 8 passed over central Iowa just one day after 100 mile per hour winds pummeled fields of corn and soybeans leaving thousands without power. The lighter shades of green in  the

Image of the Week - Landsat Archive Hits 9 Million Scenes

The Landsat archive is the world's longest continuously collected record of the Earth's surface. In mid September, it notched another milestone by adding its nine millionth scene. This particular image from north central Paraguay helps tell the kind of story that only a long historical record like Landsat can. The rectangular tracks of brown and tan that dapple the

Eyes on Earth Episode 37 – Insuring West Africa’s Crops

The Green Revolution leaned on fertilizers, drought-resistant seeds and other modern innovations to boost agricultural production across much of the planet in the second half of the 20th Century. But many of those innovations never reached West Africa, partially because the lack of social safety nets and crop insurance made such investments too risky. On this episode of

Image of the Week - Summer Fires Rage in California

As fire season continues in the western United States let's look back at a number of incidents tracked by officials across California in August. These fires were captured during the day by Landsats 7 and 8, in natural color bands of the visible spectrum. Landsat sensors also record infrared wavelengths revealing burn scars and active fires. Natural color images show smoke

Eyes on Earth Episode 35 – Watching the Water Supply with OpenET

Evapotranspiration is the process by which water transpires from the leaves and stems of plants and evaporates from the Earth’s surface. ET is an important metric for managing water use, but data availability has long been an issue. On this episode of Eyes on Earth, we talk about OpenET, a bold initiative whose goal is to improve water management by making that water

Image of the Week - Time Travel by Permafrost

In Russia's Extreme North, a widening chasm known as the Batagaika Crater provides a unique opportunity to study the past. Early declassified aerial images recorded the crater's growth in the 1960s and 1970s followed by multispectral sensor imagery captured by Landsat and Sentinel satellites, building a continuous view over the last 60 years. But the gash in the ground
