Detecting atmospheric rivers with satellite observations
Atmospheric rivers (ARs) are filaments of intense moisture transport in the atmosphere. These weather systems drive a large fraction of the extreme precipitation events over coastal regions. Detecting ARs in satellite observations has long been a cha.....»»
Enhancing hurricane forecasts: Simulations reveal reducing estimates of atmospheric friction improves storm predictions
Hurricanes and other extreme weather events are expensive in lives and money. From 1980 to 2023, weather and climate disasters caused about $2.6 trillion in damages in the U.S., according to NOAA estimates. In 2022 alone, the U.S. experienced 18 disa.....»»
NASA confirms space station cracking a “highest” risk and consequence problem
NASA and Roscosmos have not agreed on the point at which the leak rate is untenable. Enlarge / A high-resolution commercial Earth-imaging satellite owned by Maxar captured this view of the International Space Station on June 7 wi.....»»

Satellite data fusion enhances the early detection of convective clouds
As global warming continues, convective weather events are becoming more frequent. The early stage of these storms, known as convective initiation (CI), can be monitored using geostationary satellites. However, detecting CI accurately remains a chall.....»»
NOAA shares first data from GOES-19 EXIS instrument
The Extreme Ultraviolet and X-ray Irradiance Sensors (EXIS) onboard NOAA's GOES-19 satellite, which launched on June 25, 2024, are powered on, performing well, and observing the sun......»»
Study defines a safe operating space for major rivers in the Ganges Delta, India
An international study led by the University of Glasgow is the first to define a safe operating space (SOS) for major rivers in the Ganges Delta, which will enhance resilience in one of the world's most vulnerable deltas to global climate change......»»
Researchers explore novel approach to map forest dieback in satellite images
Forests and woodlands cover one third of Earth's surface and play a critical role in carbon sequestration, water regulation, timber production, soil protection, and biodiversity conservation. Accelerated by climate change, the decline of these and ot.....»»
Ice cores show pollution"s impact on Arctic atmosphere
A Dartmouth-led study on ice cores from Alaska and Greenland found that air pollution from the burning of fossil fuels reaches the remote Arctic in amounts large enough to alter its fundamental atmospheric chemistry. The findings illustrate the long.....»»
Climatologists develop more accurate El Niño Southern Oscillation forecasts
Australian climatologists closely monitor atmospheric and oceanic conditions to assess the risk of El Niño Southern Oscillation (ENSO) events occurring, which can lead to devastating natural disasters, however these predictions have become somewhat.....»»
Thousands of abandoned mines in Colorado are leaking toxic water, but Congress finally has a solution in sight
Polluted water leaking from thousands of abandoned mines in Colorado's mountains is turning wetlands orange and dumping toxic dissolved metals in the headwaters of many of the state's rivers......»»
Governor launches effort to protect rivers, water supplies as growth booms in SC
Gov. Henry McMaster took steps Tuesday to jump start plans for protecting South Carolina rivers and groundwater, forming a commission to study how to manage the water supplies that often spark disputes among businesses, farmers, environmentalists and.....»»
Atmospheric methane increase during pandemic due primarily to wetland flooding, satellite data analysis finds
A new analysis of satellite data finds that the record surge in atmospheric methane emissions from 2020 to 2022 was driven by increased inundation and water storage in wetlands, combined with a slight decrease in atmospheric hydroxide (OH). The resul.....»»

Advanced civilizations will overheat their planets within 1,000 years, researchers suggest
Earth's average global temperatures have been steadily increasing since the Industrial Revolution. According to the National Oceanic and Atmospheric Agency (NOAA), Earth has been heating up at a rate of 0.06°C (0.11°F) per decade since 1850—or ab.....»»
Better than blood tests? Nanoparticle potential found for assessing kidneys
In a study published July 29 in Advanced Materials, University of Texas at Dallas researchers found that X-rays of the kidneys using gold nanoparticles as a contrast agent might be more accurate in detecting kidney disease than standard laboratory bl.....»»
Starlink imposes $100 “congestion charge” on new users in parts of US

Study shows organonitrates in atmospheric particles vary with altitude
While atmospheric particles directly affect climate (e.g., cloud formation), sampling atmospheric particles aloft is practically challenging. Therefore, a full understanding of how particle composition is linked to environmental function remains limi.....»»
