Ground based measurements remain sparse and satellite observations rely on retrievals, so understanding intraurban, diurnal-scale changes in NO₂ is challenging. We present a novel methodology leveraging the sky scan capabilities of four Pandora spectrometers deployed around the Boston area to improve our understanding of intra-urban NO₂ variability. We collected sky scans in up to four directions per instrument per hour in addition to direct sun observations, yielding high-quality data across all site-azimuth pairs. The observations were applied to understand the role of wind conditions on driving spatial heterogeneity in column NO₂ abundance and local-scale diurnal patterns, finding that each wind type influences NO₂ differently. We leverage our experiment to understand the capabilities of the Tropospheric Emissions: Monitoring of Pollution (TEMPO) satellite instrument for tracking changes in NO₂ on intra-urban spatial scales and individual days, something that has not yet been examined in prior validation studies. Due to its value for measuring spatiotemporal variability, this approach can be used to more robustly constrain TEMPO and its uncertainties. Our comparisons with TEMPO in Boston advise caution when using data before 13 UTC as a bias persists, but in the afternoon we show that TEMPO captures similar dynamic range to the Pandoras, with differences likely attributable to spatial sampling mismatches. Our findings support the viability of a multi-azimuth sky scan experiment, and potentially broader adoption of such methodology across the global network of Pandoras.</p>","PeriodicalId":15986,"journal":{"name":"Journal of Geophysical Research: Atmospheres","volume":"131 20","pages":""},"PeriodicalIF":3.8,"publicationDate":"2026-10-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1029/2026JD047935","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149259558","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"How climate change intensifies methane emissions from inland freshwater ecosystems: mechanisms, pathways, and feedback loops","authors":"Shuang Liu, Yu Xue, Feng Zhao, Meiqi Huang, Panpan Cui, Xiaoyu Cui, Yindong Tong","doi":"10.1016/j.earscirev.2026.105747","DOIUrl":"https://doi.org/10.1016/j.earscirev.2026.105747","url":null,"abstract":"Inland freshwater ecosystems are substantial but highly uncertain sources of atmospheric methane (CH<ce:inf loc=\"post\">4</ce:inf>), and their emissions can offset part of the apparent climatic benefit of terrestrial carbon uptake. Existing assessments have often examined CH<ce:inf loc=\"post\">4</ce:inf> production, oxidation, transport, and release as separate processes, limiting understanding of how climate change alters net emissions. Here, we argue that climate change does not simply enhance individual methane-producing processes. Instead, it can reorganize CH<ce:inf loc=\"post\">4</ce:inf> cycling in inland freshwater ecosystems by simultaneously altering CH<ce:inf loc=\"post\">4</ce:inf> production, storage, oxidation, transport, and pathway-specific release. We integrate recent advances into a source-filter-release continuum that links climatic forcing, ecosystem responses, CH<ce:inf loc=\"post\">4</ce:inf> biogeochemistry, and atmospheric emission. This framework shows how warming, ice loss, hydrological change, extreme events, and altered catchment inputs reshape thermal structure, oxygen and redox conditions, substrate supply, residence time, and gas-transfer pathways. The resulting responses are nonlinear and system specific. Storage and water-column structure are often important in lakes and reservoirs, whereas transport, habitat exchange and rapid evasion commonly exert stronger controls in rivers and streams. Net emissions may increase, decrease, or shift among pathways depending on the balance among methanogenesis, oxidative filtering, retention, and release. We further evaluate mitigation options that target source strength, oxidative filtering, internal storage, and hydrodynamically mediated release, while emphasizing annual whole-system emissions and the risk of shifting emissions across seasons, locations, or pathways. This perspective provides a mechanistic basis for improving greenhouse gas accounting, climate-feedback projections, and coordinated freshwater management.","PeriodicalId":11483,"journal":{"name":"Earth-Science Reviews","volume":"6 1","pages":""},"PeriodicalIF":12.1,"publicationDate":"2026-10-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149274874","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Acoustic emission (AE) and digital image correlation (DIC) measurements were combined with fracture-surface SEM observations and main-crack-path analysis. The results showed that the mean peak nominal stress decreased from 15.17 to 5.39 MPa with increasing target surface temperature, a reduction of approximately 64.5%, while mean failure CMOD and LPD increased monotonically and reached their maxima at 600 °C. Post-peak load degradation and crack propagation occupied most of the loading history, with 97.27–99.87% of the final cumulative AE absolute energy recorded after peak load. Representative post-peak b-values were lower than pre-peak values, indicating a greater relative contribution from high-amplitude events, while tensile-type AE events dominated the RA–AF classification. DIC showed upward strain localization from the notch tip and macroscopic failure dominated by opening. Crack paths varied non-monotonically with temperature, with the greatest deflection and tortuosity at 400 °C, where path correction reduced the calculated fracture energy by approximately 11.2%. Among the representative specimens, path-corrected fracture energy peaked at 180.51 N/m at 500 °C, whereas cumulative AE absolute energy peaked at 300 °C. These findings provide an experimental basis for evaluating granite fracture following localized thermal disturbance and for thermally assisted rock breaking.","PeriodicalId":11567,"journal":{"name":"Engineering Geology","volume":"28 1","pages":""},"PeriodicalIF":7.4,"publicationDate":"2026-10-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149290949","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we analyzed two late spring–summer sediment-trap deployments conducted in 2018 and 2019 at a single shallow coastal site near Ny-Ålesund harbour, Kongsfjorden, Svalbard, together with trap-depth temperature–salinity records, treating trap-collected zooplankton as local, interval-averaged assemblage fluxes. In each deployment, four hydrographic stages and four data-derived zooplankton-flux phases were identified, with contrasting temporal patterns in hydrographic conditions and zooplankton assemblage composition. Trap-depth hydrographic conditions showed progressive warming and freshening in 2018, whereas 2019 was warmer and generally more saline during the early and middle deployment before freshening later. The 2018 zooplankton sequence was meroplankton-rich, with prominent barnacle and polychaete larval contributions followed by a short copepod/<ce:italic>Calanus</ce:italic> pulse. In 2019, a sustained <ce:italic>Calanus finmarchicus</ce:italic>-dominated sequence shifted from younger copepodites earlier to greater C4–C5 contributions later. Correlation and multivariate analyses showed that zooplankton assemblage variation was associated with trap-depth temperature–salinity conditions, while zooplankton-flux phase boundaries did not consistently coincide with hydrographic-stage boundaries. Together, these hydrographic and biological contrasts were interpreted as two conceptual assemblage-flux pathways: one meroplankton-rich in 2018 and the other <ce:italic>C. finmarchicus</ce:italic>-dominated in 2019. These pathways provide a framework for interpreting shallow near-bottom zooplankton variability and for testing whether comparable patterns recur across seasons, years and sites. This study also shows that sediment traps deployed in shallow coastal waters can provide a time-integrated perspective on local zooplankton variability.","PeriodicalId":20620,"journal":{"name":"Progress in Oceanography","volume":"83 1","pages":""},"PeriodicalIF":4.1,"publicationDate":"2026-10-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149290901","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study develops a Multiscale Constraint-Consistent Hybrid Transformer (MCC-HT), in which hydraulic consistency is embedded during trajectory generation and reservoir-level operating requirements are further reconciled through an Iterative Cumulative Rebalancing (ICR) mechanism. The framework was evaluated for the lower Jinsha River–Three Gorges six-reservoir cascade using a 64-year ten-day inflow record (1959–2022) under a deterministic hindcast setting, with comparisons against the Progressive Optimality Algorithm (POA), Particle Swarm Optimization, and two ablation variants. Over the 2015–2022 test period, MCC-HT generated annual schedules that remained consistent with the prescribed operating requirements, while reducing the average runtime for full annual schedule generation from 664.55 s for POA to 2.79 s. Under this substantial computational reduction, MCC-HT approximated the annual generation achieved by POA, with a mean difference of +0.12% that varied with hydrological conditions across individual years. Ablation results further indicate that embedded constraint handling contributes more consistently across hydrological conditions, whereas the benefit of multiscale inflow representation is more condition-dependent. These results show that structural embedding of physical constraints can support efficient and physically admissible long-horizon cascade scheduling, providing a practical basis for repeated annual scenario evaluation in strongly coupled hydro-systems.","PeriodicalId":362,"journal":{"name":"Journal of Hydrology","volume":"17 1","pages":""},"PeriodicalIF":6.4,"publicationDate":"2026-10-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149292458","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To address these questions, element fractionation in the pelite-H<ce:inf loc=\"post\">2</ce:inf>O-CO<ce:inf loc=\"post\">2</ce:inf>-NaCl system was studied experimentally at pressures of 3.0–7.8 GPa and temperatures of 750–1090 °C using the diamond trap method. Experiments on a natural pelite (without artificial trace element doping) with NaCl added simulate the conditions of warm (intermediate) and hot sediment subduction. Runs at 3.0 GPa and 750 °C yield a Cl-bearing, solute-rich fluid coexisting with an eclogitic residue that contains phengite plus accessory rutile, zircon, and monazite. At <ce:italic>P</ce:italic> ≥ 5.5 GPa and <ce:italic>T</ce:italic> ≥ 850 °C, the Cl-bearing solute-rich fluid evolves into a Cl-bearing mobile phase whose solute content is intermediate between that of a fluid and that of a supercritical liquid (SCL). With increasing pressure and temperature along a warm-subduction P-T path, the eclogite residue loses phengite, zircon and monazite, while mobile phase becomes markedly enriched in K<ce:inf loc=\"post\">2</ce:inf>O and depleted in SiO<ce:inf loc=\"post\">2</ce:inf> and Al<ce:inf loc=\"post\">2</ce:inf>O<ce:inf loc=\"post\">3</ce:inf>. At the P-T conditions of hot subduction, the system instead produces a Cl-bearing hydrous melt. The obtained data on partition coefficients between the mobile phase and the residue show that a Cl-bearing, sediment-derived mobile phase transfers LILE and LREE, and under certain conditions also Th, more efficiently than a Cl-free mobile phase does. As a result, a hydrous slab component consisting of a pelite-derived, Cl-bearing (8 wt% Cl) fluid formed at 3.0 GPa and 750 °C can generate a partial melt whose trace element pattern closely resembles that of calc-alkaline basalts. At these conditions, Cl enhances the mobility of U much more than that of Th, so that the fluid has a primitive mantle (PM) normalized Th/U ratio of ~0.2, which is inherited by the partial melt. We infer that the fingerprint of slab-derived, Cl-bearing fluids in calc-alkaline basalts is a PM-normalized Th/U ratio below 1. A hotter, pelite-derived, Cl-bearing melt, formed in the absence of residual monazite, instead leaves a fingerprint with a PM-normalized Th/U ratio above 1, which is not characteristic of calc-alkaline basalts. The same atypical fingerprint would be left by a pelite-derived, Cl-bearing SCL-like phase, which could potentially form at 5.5 GPa where slabs dip steeply (≥60°). Comparison with available data indicates that, among the hydrous slab components that can potentially form under warm subduction conditions at arc depth, only a sediment-derived, Cl-bearing fluid can generate a melt with the trace element pattern of calc-alkaline basalts.","PeriodicalId":9847,"journal":{"name":"Chemical Geology","volume":"64 1","pages":""},"PeriodicalIF":3.9,"publicationDate":"2026-10-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149274913","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we investigate this question using year-long water-rock interaction experiments with a range of lithologies (including gneiss and granite), and two starting-fluid compositions, combined with quantitative Li mass-balance modelling. Across all the experiments, dissolved δ<ce:sup loc=\"post\">7</ce:sup>Li values increased rapidly within days to weeks, reflecting preferential removal of <ce:sup loc=\"post\">6</ce:sup>Li into rapidly forming Al-bearing secondary phases and/or adsorption sites. The mass-balance results demonstrate that fluid δ<ce:sup loc=\"post\">7</ce:sup>Li values do not uniquely record weathering congruency: both monotonic and hump-shaped relationships emerge from the evolving imbalance between Li supply and removal, without requiring secondary-mineral dissolution. Moreover, δ<ce:sup loc=\"post\">7</ce:sup>Li values show only a subtle relationship with the solid reaction rate. Fluid residence time primarily determines the system's progression towards a quasi-steady-state for Li, beyond which dissolved δ<ce:sup loc=\"post\">7</ce:sup>Li values become buffered and largely insensitive to further increases in fluid residence time. These results suggest that the δ<ce:sup loc=\"post\">7</ce:sup>Li evolution reflects combined effects from weathering congruency, fluid residence time, and solid reaction rate, and thus cannot be a unique tracer for a single factor. In contrast, we propose that Li concentrations at quasi-steady-state retain information on the integrated Li release rate of the weathering solids, potentially providing complementary constraints on rock reactivity and weatherability. Overall, our results provide a new explanation for the restricted range of δ<ce:sup loc=\"post\">7</ce:sup>Li values observed in large rivers, and an updated conceptual framework for interpreting coupled Li concentration-isotope systematics in modern and ancient silicate weathering systems.","PeriodicalId":9847,"journal":{"name":"Chemical Geology","volume":"6 1","pages":""},"PeriodicalIF":3.9,"publicationDate":"2026-10-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149274914","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
