Seismic waves resonating within the upper layers of the Ross ice shelf could help scientists monitor the Antarctic melt season and understand factors that could lead to sudden ice shelf collapse.

When Floods Cross Borders, Satellite Data Can Help
With so many eyes in the sky, residents living downstream from dams now have many ways to see—and prepare for—potential dangers.
Observations Show Gravity Waves Above Antarctica Dance in Winter
Year-round observations show gravity waves above Antarctica exhibit seasonal patterns that peak in winter, which could help researchers trace the source of this mysterious phenomenon.
Earth’s Devastating Power, Seen by Satellite
Hurricanes, volcanoes, droughts, floods, fires, tsunamis: Satellites capture some of Earth’s most destructive forces.
New Analysis Provides a Fresh View of the Atmosphere on Venus
Researchers apply a radio holographic method to standard Venusian atmospheric data, resulting in outputs with finer vertical resolution and revealing small-scale atmospheric structures.
One-Pixel Views of Earth Reveal Seasonal Changes
By averaging satellite images of the Earth down to a single pixel, researchers trace how the planet’s mean color varies over time, results that inform observations of distant exoplanets.
Evaluating the Efficiency of Data Assimilation
Information is lost when researchers combine statistical models and remote sensing data, but just how much is often unclear. A new study offers a framework to measure the inefficiency.
Remote Sensing Leads to Better Understanding of Polar Regions
Fifteenth International Circumpolar Remote Sensing Symposium; Potsdam, Germany, 10–14 September 2018
Improving Retrievals for Partially Cloudy Pixels
Cloud retrievals for partly cloudy pixels might be able to be improved by using high-resolution samples in a visible to near-infrared band, which many satellite sensors offer.
Satellite Observations Validate Stratosphere Temperature Models
Since the 1970s, the stratosphere has cooled as ozone levels dropped and carbon dioxide levels increased. Chemical models of the temperature decline conflicted with satellite observations—until now.
