Atmosphere survival model refines search for habitable planets
Atmosphere survival model refines search for habitable planets Gaby Clark Scientific Editor Robert Egan Associate Editor Researchers have developed the Smaller Than Earth Habitability Model (STEHM) to assess which planets can maintain life-supporting atmospheres, focusing on size and atmospheric dynamics. Since 1992, NASA has confirmed the existence of over 6,000 planets outside of our solar system, and over 7,000 suspected planets still await confirmation. These distant planets, dubbed...
Super Typhoon Sinlaku triggered atmospheric gravity waves visible from space
Super Typhoon Sinlaku triggered atmospheric gravity waves visible from space A record-early super typhoon sent giant atmospheric ripples into near-space, offering scientists a new clue for tracking powerful storms. - Date: - June 3, 2026 - Source: - NASA Earth Observatory - Summary: - One of the most powerful typhoons ever recorded this early in the Pacific season did more than unleash flooding and extreme winds—it sent enormous ripples all the way into the upper atmosphere.
Atmospheric Methane Removal as a Third Climate Intervention: Termination Risks and Air Pollutant Effects
Physics > Atmospheric and Oceanic Physics [Submitted on 24 Jan 2026 (v1), last revised 29 May 2026 (this version, v3)] Title:Atmospheric Methane Removal as a Third Climate Intervention: Termination Risks and Air Pollutant Effects View PDFAbstract:Atmospheric Methane Removal (AMR) is a third class of climate intervention, along with Carbon Dioxide Removal (CDR) and Solar Radiation Management (SRM). We show that, unlike CDR, the avoided warming by AMR is not durable due to methane's short...
TianJi-Environ: An Autonomous AI Scientist for Atmospheric Environmental Research
arXiv:2606.07697v1 Announce Type: cross Abstract: As atmospheric environmental prediction continues to improve, interpretable validation of pollution mechanisms and feedback processes has become a main challenge in atmospheric chemistry. Yet mechanism validation based on complex numerical models still relies heavily on expert knowledge: mechanistic hypotheses must be operationalized into executable experiments, and model outputs must be organized into traceable evidence. We present...

The relationship between atmospheric stratification and internal wave processes
new Abstract: The atmosphere is a resonant system and its oscillation spectrum is determined by the spatial distribution of parameters. For example, the frequency of internal gravity waves depends on the vertical temperature gradient. Therefore, the study of the spectra of internal wave processes can be used to estimate the spatial distribution of atmospheric parameters.
Set-Based Transformer for Atmospheric Compensation in Standoff LWIR Hyperspectral Imaging
Announce Type: new Abstract: Passive long-wave infrared (LWIR) hyperspectral imaging under a standoff geometry depends on atmospheric absorption and emission, as well as reflected radiance, thus making atmospheric compensation essential to get knowledge of a target of interest. Despite its importance, this compensation has been largely overlooked due to its practical and modeling difficulty.
PRISM: Rethinking Atmospheric Scattering Reconstruction as a Unified Understanding and Restoration Model for Real-world Dehazing
arXiv:2604.07048v2 Announce Type: replace Abstract: Real-world image dehazing (RID) aims to remove haze-induced degradation from real scenes. This task remains challenging due to non-uniform haze distribution, spatially varying color shifts, and the scarcity of paired real hazy-clean data. In PRISM, we propose Proximal Scattering Atmosphere Reconstruction (PSAR), a physically structured framework that jointly reconstructs the clear scene and scattering variables under the atmospheric...
'I would never have guessed it': Unexpected effect is squeezing Mars' atmosphere like toothpaste, experts say
The article discusses the unexpected effect of a powerful coronal mass ejection on Mars' atmosphere, which was detected by NASA's MAVEN spacecraft in 2023. The event caused strange "wiggles" in the atmosphere, which were a tell-tale sign of the Zwan-Wolf effect, previously thought to be impossible on Mars. The effect is similar to squeezing toothpaste, and experts were surprised by its occurrence on the Red Planet.
