++Important TIRS calibration notice from USGS, Jan. 6, 2014: “Due to the larger calibration uncertainty associated with TIRS band 11, it is recommended that users refrain from relying on band 11 data in quantitative analysis of the TIRS data, such as the use of split window techniques for atmospheric correction and retrieval of surface temperature values.”

We suggest that Band 10 be used in conjunction with an atmospheric model to estimate surface brightness temperature. Our calibration team has found that with current processing these surface brightness temperatures are accurate to within ~±1 K for many 15 – 35° C targets, e.g., growing season vegetated targets.

Dec 12, 2016 • NASA/USGS Satellite Provides Global View of Speed of Ice

Glaciers and ice sheets move in unique and sometimes surprising patterns, as evidenced by a new capability that uses Landsat 8 satellite images to map the speed of flowing ice in Greenland, Antarctica and mountain ranges around the world. The project aims to better understand how ice flow is changing worldwide – and its impact on sea level.

From the Arctic to the Mojave Desert, terrestrial and marine habitats are quickly changing. Satellites are particularly well-suited to observe habitat transformation and help scientists forecast what animals might do next.

Oct 26, 2016 • Paw Paw Bends

The Operational Land Imager (OLI) on Landsat 8 captured this image of the Potomac River and canal on September 27, 2016. The image shows the stretch between Hancock and Cumberland, Maryland—about 97 kilometers (60 miles) if you were to hike or bike along the towpath between these two towns. West Virginia is south of the river.

Oct 25, 2016 • NASA Awards Contract for Sustainable Land Imaging Spacecraft

NASA has awarded a delivery order under the Rapid Spacecraft Acquisition III (Rapid III) contract to Orbital Sciences Corporation of Dulles, Virginia, known publicly as Orbital ATK, for the Landsat 9 spacecraft.

Aug 1, 2016 • Acadia National Park

Acadia National Park is one of the most visited parks in America, drawing more than 2.5 million visitors per year to the craggy, jagged coast of Maine. The park is celebrating its 100th anniversary in 2016. On September 6, 2015, the Operational Land Imager (OLI) on the Landsat 8 satellite acquired these images of the park and its surroundings.

Jul 7, 2016 • As the Rains Start: Using NASA Data to Automatically Detect Potential Landslides in Nepal

A team of scientists using NASA satellite data designed an automated system to quickly identify landslides that often go undetected and unreported.
