Discover and Access the OPERA-DISP Dataset Using ASF DAAC’s Displacement Portal

By Lurker,
Many scientists are interested in using interferometric synthetic aperture radar (InSAR) data to monitor the motion of Earth’s surface, but the analyses required can be complex, and the data are often challenging to work with. To simplify these analyses, the Jet Propulsion Laboratory (JPL) Observational Products for End-Users from Remote Sensing Analysis (OPERA) team has created an OPERA Surface Displacement (OPERA-DISP) dataset. This dataset provides InSAR-derived surface displacement measureme
Swiss glacier collapses, burying village

By Lurker,
A Swiss Alpine village has been buried by a massive debris field after a glacier collapsed on a nearby mountain. Reuters reports that 90% of Blatten, Switzerland is engulfed by ice, mud, and rock after what scientists suspect is a dramatic display of the impact of climate change on mountain communities.
"It’s critical to realize that we now have left the space of historical precedence and entered an era where we face new hazards from locations that have never been a problem in the past and
Earth Observing Satellites Online Compendium

By Lurker,
The Joint Agency Commercial Imagery Evaluation (JACIE) Earth Observing Satellites Online Compendium contains details about past, present and future Earth observing satellites and the sensors they carry.
Derived from print versions of Compendiums published in 2019, 2020, and 2022, this resource has been developed and is managed by the Requirements, Capabilities and Analysis for Earth Observation (RCA-EO) team at the USGS Earth Resources Observation and Science (EROS) Center in Sioux Falls,
GRIT remaps the world's rivers, branching into the unknown to aid global flood modeling

By Lurker,

The most comprehensive map of the world's rivers has been constructed by a group of academics at the University of Oxford. This map represents a significant step forward in terms of flood forecasting, climate risk planning, and water resource management in a world that is warming.
The new research, which was published in the journal Water Resources Research, features the introduction of GRIT, a mapping method that ultimately demonstrates how rivers actually flow, branch, and connect landsc
A breakthrough in high-speed, eye-safe LIDAR is made possible by heavy-metal-free quantum dots

By Lurker,
There are many different frequencies of light that reach Earth, some of which are visible to us and others of which are not. Because of its special characteristics, shortwave infrared (SWIR) stands out among these frequencies and is very helpful for Light Detection and Ranging (LIDAR) systems.
Like SONAR, which utilizes sound waves to determine distances, LIDAR employs laser pulses.
The danger of SWIR waves is that they do not reach the retina through the cornea and lens of the huma
