Great frigatebirds live in tropical regions and routinely fly to 2,000 meters (1.25 miles) in altitude, occasionally reaching heights of 4,000 meters (2.5 miles). A new study shows that great frigatebirds equipped with tiny sensors can give detailed information about the planetary boundary layer (PBL), which is the dynamic atmospheric layer that is closest to ...

In August, when heavy rain hit parts of Chile, tens of thousands of people had to evacuate their homes as their communities flooded. Many got a warning a couple of days in advance, thanks to a tool from Google called Flood Hub that rolled out in the country earlier this year. Before Flood Hub existed, ...

While some parts of the world suffer extreme heat and persistent drought, others are being flooded. Overall, continental water volumes vary so much over time that global sea levels fluctuate significantly too. By combining the hydrological model WaterGAP with GRACE satellite data, a team of geodesists at the University of Bonn have come up with ...

ESA along with European Organisation for the Exploitation of Meteorological Satellites (Eumetsat) today have released the first animations from the Lightning Imager onboard the first Meteosat Third Generation satellite, which launched on 13 December 2022.

Using forecasts run on a NASA supercomputer, scientists from Oak Ridge National Laboratory (ORNL); NASA Goddard Space Flight Center; the University of California, Berkeley; and the Korea National University of Transportation assessed the ability of NASA’s Goddard Earth Observing System Subseasonal to Seasonal Version 2 (GEOS-S2S-2) forecasting system to predict atmospheric and land surface conditions ...

Deep learning is a fundamental technique in modern Artificial Intelligence and is being applied to disciplines across the scientific spectrum; earth science is no exception. Yet, the link between deep learning and Earth sciences has only recently entered academic curricula and thus has not yet proliferated. Deep Learning for the Earth Sciences delivers a unique ...

NASA and Rocket Lab launched two of the agency’s CubeSats on Sunday to study tropical cyclones with greater frequency than existing satellites, according to an agency announcement. The CubeSats were launched on an Electron Rocket from Rocket Lab’s Launch Complex in New Zealand at 9pm EDT on Sunday—or 1pm NZST on Monday. The launch was ...

Carbon Brief reveals visually just how much the world’s most populous regions have been affected by extreme heat since 2013.

The National Oceanic and Atmospheric Administration (NOAA) has selected Oklahoma City along with 17 other communities to participate in the 2023 NOAA Urban Heat Island (UHI) mapping campaign. Pending City Council approval, the campaign will kick off this summer, with volunteer citizen scientists using heat sensors mounted on their cars to map the hottest parts ...

Google has announced a series of measures to provide up-to-date and actionable information to help people and cities cope with rising temperatures due to climate change. These initiatives include new extreme heat alerts on Google Search, the expansion of the Tree Canopy tool for urban planning, and a $5 million investment in the World Resources ...

Live flood alert InsurTech platform Previsico has partnered with the new €4.3bn Meteosat Third Generation satellite system. This new system will allow Previsico to be more accurate and timelier with flood warnings, providing insurers and property owners with more time to mitigate flood impacts. The first satellite of the new generation was launched on 13 ...

Just four days after heavy rain hit California, the state was drenched with another atmospheric river on January 4 and 5, 2023. A plume of moisture from the tropical Pacific interacted with a low-pressure system that rapidly strengthened over the northeast Pacific, producing a storm that caused flooding, toppled trees, and downed power lines. This ...

NOAA has declared the Geostationary Operational Environmental Satellite (GOES)-18 fully operational as GOES West, marking a significant milestone for severe weather detection in the Western Hemisphere. Launched on March 1, 2022, the primary instrument aboard GOES-18 is the L3Harris high-resolution, Advanced Baseline Imager (ABI). L3Harris also produced the enterprise ground system which processes the imagery ...

For decades, satellites have been keeping a watchful eye on Earth, relaying increasingly precise, detailed and timelier information than ever before. Armed with the right mathematical tools, we can use this information to anticipate and mitigate climate extremes and associated hazards—from floods to landslides. So why isn’t this happening now? To harness its full potential, ...

Peter Manshausen at the University of Oxford and his colleagues have found that clouds that had appeared unaffected are in fact affected by the aerosols. The researchers mapped the paths of two million ships in the Atlantic Ocean over a six-year period and used a global database for the winds on the trade routes the ...

The Urban Heat Island (UHI) is an area of growing interest for many people studying the urban environment and local/global climate change. The UHI has been scientifically studied for 200 years and, although it is an apparently simple phenomenon, there is considerable confusion around the different types of UHI and their assessment. The Urban Heat ...

Using older models and newer methods, Hu and the team of scientists conclude that ants and photons are extremely alike in the realm of snow-depth research. This helped the principle come to fruition that light bouncing around in snow would produce gaugable and viable results. ICESat-2 (Ice, Cloud, and Land Elevation Satellite-2) now reads light ...
