Trends in Chinese horizontal visibility, the frequency of visibility >19 km, and haziness for period between 1981 2005 were evaluated based on data daily visibility. Annual means calculated each station China as a whole. Linear regression analysis was used to characterize long‐term annual trends these variables. Over past 25 years, there has been significant decrease (−2.1 km per decade from 1990 2005) (−3.5% decade) but increase 75th percentile extinction coefficients (25% year)....
Existing projections of wetland methane emissions usually neglect feedbacks from global biogeochemical cycles. Using data-driven approaches, we estimate 2000 to 2100, considering effects meteorological changes and atmospheric sulfate deposition CO 2 fertilization. In low-CO scenarios (1.5° 2°C warming pathways), the suppressive effect on largely diminishes by 2100 due clean air policies, with resulting emission increases (7 ± Tg a −1 ) being 35 22% total changes. mid-CO (2.4° 3.6°C modestly,...

Abstract Deep learning techniques have significantly advanced the field of protein structure prediction. LOMETS3 (https://zhanglab.ccmb.med.umich.edu/LOMETS/) is a new generation meta-server approach to template-based prediction and function annotation, which integrates newly developed deep threading methods. For first time, we extended handle multi-domain proteins construct full-length models with gradient-based optimizations. Starting from FASTA-formatted sequence, performs four steps...
Abstract. Almost USD 3 billion per year is appropriated for wildfire management on public land in the United States. Recent studies have suggested that ongoing climate change will lead to warmer and drier conditions western States, with a consequent increase number size of wildfires, yet large uncertainty exists these projections. To assess influence future changes cover lightning-caused wildfires national forests parks States consequences fires air quality, we link dynamic vegetation model...
Updated preindustrial fire emissions consistent with ice core records reduce the magnitude of estimated aerosol radiative forcing.
Abstract. Reducing methane (CH4) emissions from the oil and gas (O&G) sector is crucial for mitigating climate change in near term. MethaneSAT an upcoming satellite mission designed to monitor basin-wide O&G globally, providing estimates of emission rates helping identify underlying processes leading release atmosphere. data will support advocacy policy efforts by track reduction commitments targets set countries industries. Here, we introduce a CH4 retrieval algorithm based...
Hotel housekeepers are exposed to stressors at work and outside of work. A minimal amount is known about these workers' pathophysiological responses those stressors. Allostatic load a concept increasingly used understand pathophysiologic manifestations individuals' bodily response stress. The purpose this study was examine the associations between nonwork stressors, allostatic load, health outcomes among hotel housekeepers. Work (e.g., number traumatic events, everyday discrimination, job...
Abstract. The MethaneSAT satellite instrument and its aircraft precursor, MethaneAIR, are imaging spectrometers designed to measure methane concentrations with wide spatial coverage, fine resolution, high precision compared currently deployed remote sensing instruments. At 12 960 m cruise altitude above ground (13 850 sea level), MethaneAIR datasets have a 4.5 km swath gridded 10 × pixels 17–20 ppb standard deviation on flat scene. was in the summer of 2021 Permian Basin test accuracy...

Abstract Land snails exhibit the potential for capturing synoptic‐scale precipitation events through δ 18 O records of their shells (δ shell ), but application is hindered by absence a practical methodology tracking these events. Here, we developed statistical to track from daily resolved snail body fluid BF ) record. We further tested and verified our approach using modern Cathaica fasciola Chinese Loess Plateau (CLP). The reconstructed 3‐day‐timescale frequencies first derivations shows...
In June 2023, an elevated smoke layer from record-breaking Canadian wildfires was transported across the eastern half of United States, impacting air quality for millions people. Houston, TX experienced a notable biomass burning (BB) event associated with this wildfire Jun 4 to 9, 2023. The vertical transport down surface followed afternoon convective activity in Houston urban area on 6–8. Our monitoring sites at urban, rural, and coastal locations around different levels smoke. Carbon...
Mesoscale atmospheric chemical transport models, while widely used for studying chemistry, face significant challenges in capturing fine-scale processes complex environments such as urban areas and wildfire smoke plumes. The coarse spatial resolution of these models limits their ability to resolve turbulent transport, sharp concentration gradients, nonlinear interactions driven by subgrid-scale dynamics. To address limitations, we apply the high-resolution Weather Research Forecasting model...

Abstract. Climate models predict a shift toward warmer and drier environments in southwestern North America. The consequences of such for dust mobilization concentration are unknown, but they could have large implications human health, given the connections between inhalation disease. Here we link dynamic vegetation model (LPJ-LMfire) to chemical transport (GEOS-Chem) assess impacts future changes three factors – climate, CO2 fertilization, land use practices on this region. From there,...
Wildfires in North America, particularly western states, have caused widespread environmental, economic, social, and health impacts. Smoke from these fires travels long distances, spreading pollutants worsening the air quality across continents. Vulnerable groups, such as children, elderly, those with preexisting conditions, face heightened risks, do firefighters working extreme conditions. Wildfire are of particular concern they fighting conditions minimal protective equipment. This study...
