1. Geostationary Satellites Total Ozone Observations: First Results on Ground-Based Networks Validation Efforts for TEMPO and GEMS.
1. 地球静止轨道卫星总臭氧观测：TEMPO和GEMS地基网络验证工作的首批结果PMID:日期:2025-06-28The Tropospheric Emissions: Monitoring of Pollution (TEMPO) instrument, launched in April 2023, is North America's first geostationary air pollution monitoring satellite mission. Together with Asia's Geostationary Environment Monitoring Spectrometer (GEMS) launched in 2020 and Europe's upcoming Sentinel-4, TEMPO contributes to nearly global coverage provided by geostationary satellite constellation. TEMPO and GEMS offer hourly, high-resolution data of ozone surpassing the once-daily observations of instruments like the TROPOspheric Monitoring Instrument (TROPOMI) in temporal resolution. This study presents TEMPO's total ozone data, demonstrating TEMPO's ability to observe sudden changes in ozone and UV index. Furthermore, TEMPO and GEMS measurements are validated using ground-based monitoring networks (Brewer, Dobson, and Pandora). Results show good agreement but also highlight latitude-dependent discrepancies between the satellite and ground-based data sets (-2% to 2% for TEMPO, -1% to -3% for GEMS). Findings are further validated using TROPOMI data and reanalysis models.

2. {"_":" Enrichment in Mesoscale Eddies of the Great Atlantic Belt.","i":["Sargassum","Sargassum"]}
PMID:日期:2025-03-28Pelagic has increased dramatically in the past decade, primarily in the annually recurrent Great Atlantic Belt (GASB) that extends from the coast of West Africa to the Gulf of Mexico. Using satellite observations of density and mesoscale eddies from 2011 to 2023, we investigate whether more can be found in mesoscale eddies. Cyclonic eddies were found to contain 6%-47% more (relative to eddy-free waters) across all selected regions within the GASB, with the highest density in their inner cores (<0.5 eddy radius). Impacts of anticyclonic eddies were weaker and varied between regions. In addition, enrichment tended to be higher in eddies with greater size or amplitude, such as the North Brazil Current rings and those in the Caribbean Sea. These findings may inform mitigation strategies, for example, through physical removal in targeted locations.

3. The Dayside Ionosphere of Mars as Controlled by the Interplay Between Solar Wind Dynamic Pressure and Crustal Magnetic Field Strength.
PMID:日期:2024-11-22We investigate how the Martian dayside ionospheric structure is modified by crustal magnetic field (CMF) strength and upstream solar wind pressure by analyzing electron density data from the Langmuir Probe and Waves instrument onboard the MAVEN (Mars Atmosphere and Volatile EvolutioN) spacecraft. We find that the electron density above the exobase is anticorrelated with the ratio of solar wind's normal dynamic pressure ( ) to CMF magnetic pressure ( ). We also analyze the electron density behavior across different magnetic topologies as a function of . The extremely low electron density in the draped topology relates to ionopause-like structures. The lower electron density in the closed and open topology under higher may be attributed to a downward force, potentially the × force in the case of closed topology. This study highlights the complex interplay between solar wind and CMF in influencing the Martian dayside upper ionosphere.

4. Distilling the Evolving Contributions of Anthropogenic Aerosols and Greenhouse Gases to Large-Scale Low-Frequency Surface Ocean Changes Over the Past Century.
4. 提炼过去一个世纪人为气溶胶和温室气体对大规模低频表面海洋变化的不断演变贡献PMID:日期:2024-11-22Anthropogenic aerosols (AER) and greenhouse gases (GHG)-the leading drivers of the forced historical change-produce different large-scale climate response patterns, with correlations trending from negative to positive over the past century. To understand what caused the time-evolving comparison between GHG and AER response patterns, we apply a low-frequency component analysis to historical surface ocean changes from CESM1 single-forcing large-ensemble simulations. While GHG response is characterized by its first leading mode, AER response consists of two distinct modes. The first one, featuring long-term global AER increase and global cooling, opposes GHG response patterns up to the mid-twentieth century. The second one, featuring multidecadal variations in AER distributions and interhemispheric asymmetric surface ocean changes, appears to reinforce the GHG warming effect over recent decades. AER thus can have both competing and synergistic effects with GHG as their emissions change temporally and spatially.

5. Climate-Induced Saltwater Intrusion in 2100: Recharge-Driven Severity, Sea Level-Driven Prevalence.
PMID:日期:2024-11-22Saltwater intrusion is a critical concern for coastal communities due to its impacts on fresh ecosystems and civil infrastructure. Declining recharge and rising sea level are the two dominant drivers of saltwater intrusion along the land-ocean continuum, but there are currently no global estimates of future saltwater intrusion that synthesize these two spatially variable processes. Here, for the first time, we provide a novel assessment of global saltwater intrusion risk by integrating future recharge and sea level rise while considering the unique geology and topography of coastal regions. We show that nearly 77% of global coastal areas below 60° north will undergo saltwater intrusion by 2100, with different dominant drivers. Climate-driven changes in subsurface water replenishment (recharge) is responsible for the high-magnitude cases of saltwater intrusion, whereas sea level rise and coastline migration are responsible for the global pervasiveness of saltwater intrusion and have a greater effect on low-lying areas.

6. Controls on Erosion and Cyclic Step-Formation Upstream of Waterfalls.
PMID:日期:2024-11-22Waterfall retreat transmits base-level perturbations upstream, thereby providing markers of changing climate and tectonics. In homogeneous rock, waterfalls often retreat either by direct waterfall-face erosion or incision from repeating ('cyclic') steps formed above waterfalls. We lack knowledge on the conditions driving these different erosion styles, limiting our ability to predict waterfall retreat. We address this knowledge gap through flume experiments assessing how changing flow hydraulics modulates bedrock erosion. We show that, under large discharges, changes in flow hydraulics cause spatial variability in particle impact velocity, leading to cyclic step formation. As discharge decreases, both the magnitude and spatial variability of particle impact velocity decreases, causing more uniform erosion, limiting cyclic step development and potentially allowing direct erosion of the waterfall face to become the dominant retreat mechanism. These results suggest climate change and water-resource management can alter the rate and style of waterfall retreat.

7. Coastal Supra-Permafrost Aquifers of the Arctic and Their Significant Groundwater, Carbon, and Nitrogen Fluxes.
PMID:日期:2024-11-21Fresh submarine groundwater discharge (FSGD) can deliver significant fluxes of water and solutes from land to sea. In the Arctic, which accounts for ∼34% of coastlines globally, direct observations and knowledge of FSGD are scarce. Through integration of observations and process-based models, we found that regardless of ice-bonded permafrost depth at the shore, summer SGD flow dynamics along portions of the Beaufort Sea coast of Alaska are similar to those in lower latitudes. Calculated summer FSGD fluxes in the Arctic are generally higher relative to low latitudes. The FSGD organic carbon and nitrogen fluxes are likely larger than summer riverine input. The FSGD also has very high CO making it a potentially significant source of inorganic carbon. Thus, the biogeochemistry of Arctic coastal waters is potentially influenced by groundwater inputs during summer. These water and solute fluxes will likely increase as coastal permafrost across the Arctic thaws.

8. Enablement or Suppression of Collisionless Magnetic Reconnection by the Background Plasma Beta and Guide Field.
8. 背景等离子体β和引导场对无碰撞磁重联的触发或抑制PMID:日期:2024-11-21How magnetic reconnection is triggered or suppressed is an important outstanding problem. By considering pinching of a current sheet that has formed at non-equilibrium, we show that the background plasma beta is a major controlling factor in the onset and nature of magnetic reconnection. A high plasma beta inhibits a current sheet from pinching down to kinetic scales required for collisionless reconnection, while a low beta facilitates it. A simple adiabatic model provides a good prediction for the reconnection-enabled regions in thickness versus peak plasma beta space, which are confirmed by a series of particle-in-cell simulations with varying initial parameters. A strong dependency of the peak reconnection rate on the plasma beta is clearly predicted with reconnection being favored in low beta conditions. A finite guide field is an additional source of reconnection suppression, consistent with previous observations that reconnection requires a large enough magnetic shear angle for high-beta situations.

9. Light Limitation of Poleward Coral Reef Expansion During Past Warm Climates.
PMID:日期:2024-11-21The latitudinal range of modern shallow-water tropical corals is controlled by temperature, and presently limited to waters warmer than 16-18°C year-round. However, even during Cenozoic climates with such temperatures in polar regions, coral reefs are not found beyond >50° latitude. Here, we test the hypothesis that daily available solar radiation limited poleward expansion of coral reefs during warm climates, using a new box model of shallow marine coral calcification. Our results show that calcification rates start to decline beyond 40° latitude and drop severely beyond 50° latitude, due to decreasing winter light intensity and day length, irrespective of aragonite saturation. This suggests that light ultimately prohibits further poleward expansion in warm climates. In addition, fossil coral reef distribution is not a robust proxy for water temperatures and poleward expansion of reefs beyond 50° latitude is not an expected carbon cycle feedback of climate warming.

10. Dominating Remote Source and Its Potential Contribution of Airborne Dust Over the Tibetan Plateau.
PMID:日期:2024-11-21Dust particles, transported over long-distances and driven by westerly winds, dominate high-altitude (>4 km) snow darkening and melting over the Tibetan Plateau (TP). A systematic assessment of their remote sources and potential contributions remains limited. In this paper, we present a novel algorithm for source-tracing of airborne dust designed to tackle the aforementioned challenges. The algorithm effectively constrains dust activity and guarantees precise tracking through using satellite and reanalysis-based estimates. The high-altitude airborne dust over the TP shows considerable spatial variation and primarily comes from the desert clusters in Central Asia, West Asia, and South Asia. The Karakum, Taklimakan, and Thar deserts are significant sources of high-altitude airborne dust in the northwest, northeast, and southwest regions of TP, with average mass loadings (mg m) contributing rates of 42.2% (32.9), 49.6% (48.3), and 16.4% (32.1), respectively. The results demonstrate significant differences in how adjacent deserts affect high-altitude snowmelt in the TP.
