The SWOT mission captured the flood waves, which stretched from 47 to 166 miles long, as they traveled down rivers in Montana, Texas, and Georgia. In a first, researchers from NASA and Virginia Tech used satellite data to measure the height and speed of potentially hazardous flood waves traveling down U.S. rivers. The three waves they tracked were likely caused by extreme rainfall and by a

A recent study led by scientists at the Guangzhou Institute of Geochemistry of the Chinese Academy of Sciences (GIG-CAS), in collaboration with international partners, uncovers how deeply subducted carbonates reshape the Earth's mantle chemistry, influencing both diamond formation and the evolution of cratonic lithosphere. Using high-pressure experiments that simulate depths from 250 to 66

CloudCatcher, a citizen science program developed by STFC RAL Space, is inviting the public to help improve the accuracy of cloud detection in satellite imagery. The project plays a vital role in enhancing how scientists measure Earth's surface temperatures from space by verifying when clouds obstruct the satellite's view. This latest version of CloudCatcher builds on the success of a 2020

Microsoft has developed an artificial intelligence (AI) model that beats current forecasting methods in tracking air quality, weather patterns, and climate-addled tropical storms, according to findings published Wednesday. Dubbed Aurora, the new system - which has not been commercialised - generated 10-day weather forecasts and predicted hurricane trajectories more accurately and faster th
