  text: 'Air pollution is a critical public health issue worldwide, South America
    faces unique challenges due to rapid urban growth, industrial expansion, and recurrent
    biomass burning. Existing studies have largely focused on regional or national
    scales, overlooking detailed spatio-temporal dynamics in cities. This study provides
    a comprehensive assessment of air pollution spatio-temporal trends from 2013 to
    2023 in six major South American cities: Bogotá, Buenos Aires, Montevideo, Quito,
    Santiago de Chile, and São Paulo. We evaluated four key pollutants, NO2, O3, PM10,
    and PM2.5, using in situ monitoring networks complemented with reanalysis (boundary
    layer and pollution dynamics), and fire detections datasets (biomass burning).
    A key innovation is the use of a Lagrangian Tracker, which identifies persistent
    hotspots and transport pathways of pollutants, offering new insights into transboundary
    pollution. Results show that nearly all cities experienced reductions in particulate
    matter concentrations, while three of the six cities exhibited rising O3 levels,
    reflecting complex interactions between emissions, meteorology, and atmospheric
    chemistry. Santiago de Chile recorded the highest levels of NO2 and PM, strongly
    influenced by topography and biomass burning in JJA. Bogotá and Quito were notably
    impacted by regional fire emissions, whereas coastal cities such as Buenos Aires
    and Montevideo benefited from greater pollutant dispersion but still exceeded
    the World Health Organization guidelines. By integrating ground-based, satellite,
    and reanalysis data with advanced trajectory modeling, this research provides
    detailed spatio-temporal evaluations of air pollution in South America and highlights
    the urgent need for coordinated regional strategies to reduce health and economic
    burdens.'

  text: Tropospheric ozone has the potential to become an increasingly pressing public
    health issue in Bogotá, Colombia, due to rising concentrations across the city
    driven by complex interactions among emissions, meteorology, and urban structure.
    This study presents a comprehensive spatiotemporal analysis of ozone levels from
    2013 to 2023 and assesses the associated health burden using mortality data from
    the same period. Results reveal a consistent upward trend in ozone concentrations,
    particularly in northern, western, and southern localities, with seasonal peaks
    linked to biomass burning and photochemical conditions. Mortality analysis, based
    on the Global Exposure Mortality Model, estimates that 18.3% of all deaths among
    individuals aged 25 and older are attributable to long-term ozone exposure. The
    highest burdens are found in densely populated and socioeconomically vulnerable
    areas such as Kennedy, Suba, and Ciudad Bolívar, with the elderly being the most
    affected. Building on these findings, we developed a machine learning prediction
    model for ozone using a convolutional merge with a long-short term memory network
    architecture trained on air quality and meteorological variables. The model demonstrated
    strong predictive performance (mean Rho=0.86, RMSE=3.5 μg/m3) across monitoring
    stations (17 with at least 35000 data points), supporting its potential application
    in real-time early warning systems across Bogotá. This integrated approach highlights
    the importance of localized air quality management, combining epidemiological
    assessment with predictive modeling. The findings underscore the urgency of implementing
    region-specific mitigation strategies and improving monitoring infrastructure
    to reduce health risks from ozone exposure in Bogotá’s rapidly growing urban environment.

  text: Tropical shallow clouds are a major source of uncertainty in Earth's climate
    sensitivity, especially through their spatial arrangement, which global climate
    models do not represent. Efforts to understand their organization have partly
    relied on classifying observed scenes, identifying four patterns as archetypal
    regimes. Here we analyze geostationary satellite imagery of the western tropical
    Atlantic using the L‐function, a tool based on point pattern theory that quantifies
    cloud organization across spatial scales. Classical examples of the four patterns
    show distinct L‐function fingerprints, revealing their characteristic clustering
    and regularity scales and aiding physical interpretation. Yet, when evaluating
    many scenes at fixed spatial scales, the L‐function distribution lacks the distinct
    modes expected from discrete regimes. This is corroborated by analyses of other
    organization indices employing diverse approaches, from inter‐cloud nearest‐neighbor
    distances to fractal analysis. Implications for the parameterization of mesoscale
    cloud organization in climate models are discussed.

  text: This study investigates the mechanisms driving clustered convection and the
    breakdown of the Intertropical Convergence Zone (ITCZ) over the Western Pacific
    Warm Pool using high‐resolution cloud‐resolving simulations and machine‐learning
    sensitivity experiments. Results show that ITCZ breakdown episodes, marked by
    spatially homogeneous convection and weakened meridional moisture gradients, are
    triggered primarily by anomalous moisture advection linked to the equatorial Rossby‐wave
    activity. While large‐scale moisture advection regulates the background convective
    state strongly, it is the surface and low‐level meridional winds that dominate
    transitions between clustered and random convection. Simulations demonstrate that
    moisture alone can sustain convective clustering, but breakdown episodes are more
    persistent and widespread when coupled with southerly meridional advection. These
    findings confirm that wave‐driven advection acts as a regulatory mechanism, periodically
    disrupting convective clustering and reshaping the meridional moisture gradient.
    This modulation of organization by wave‐induced breakdown events is critical for
    understanding tropical convection variability and its implications for the climate
    system.

  text: 'Global emission inventories often fail to capture the complexities of vehicular
    pollution in regions with unique fuel mixes, such as Brazil’s extensive biofuel
    use, leading to significant uncertainties in atmospheric modeling. This study
    presents a century-long (1960–2100) bottom-up vehicular emission inventory for
    Brazil, leveraging locally derived emission factors. Our estimates reveal substantial
    discrepancies in magnitude, timing, and speciation of non-CO2 pollutants (CO,
    NMHC, PM2.5) compared to leading global inventories (EDGAR, CEDS, CAMS), highlighting
    critical inaccuracies in widely used data sets. More critically, future projections
    under Shared Socioeconomic Pathways (SSPs) uncover a novel positive feedback mechanism:
    rising temperatures significantly enhance vehicular evaporative nonmethane hydrocarbon
    (NMHC) emissions. This temperature-dependent increase and subsequent NMHC oxidation
    to CO2 suggest an overlooked pathway that could amplify climate warming and air
    pollution globally, particularly after a breakpoint around 2050 (p < 0.05). While
    historical emissions peaked in the 1990s–2000s, nonexhaust PM becomes increasingly
    important. Air quality simulations using our inventory in the MUSICA model show
    good regional PM2.5 agreement but highlight challenges in resolving local primary
    pollutant peaks. This comprehensive inventory provides crucial data for Brazil
    and uncovers globally relevant climate–chemistry interactions, urging a re-evaluation
    of regional specificities in global emission assessments.'

  text: We examine mesoscale convective organisation in the tropical western Pacific
    using a multivariate analysis of column humidity, precipitation and sea surface
    temperature (SST) observations. We demonstrate that in boreal summer and autumn,
    convection remains spatially random despite radiative-feedbacks acting to aggregate
    convection, which we attribute to the high density of convective moisture sources
    and the role of wind shear. Instead, in winter and spring, a weak meridional SST
    gradient exists and convection is usually clustered over the regions of warmer
    SSTs, with significant meridional humidity gradients. However, this is sporadically
    interrupted by episodes of convection migration to the coldest SSTs and limited
    spatial humidity variance. These episodes are the result of westward propagating
    equatorial waves, which remove meridional humidity gradients. It appears that
    the drivers of mesoscale convective clustering and humidity variability in the
    Pacific warm pool are the SST gradients, shear, and equatorial wave dynamics.

  text: 'Recently, Biagioli and Tompkins (2023, https://doi.org/10.1029/2022ms003231)
    used a simple stochastic model to derive a dimensionless parameter to predict
    convective self aggregation (SA) development, which was based on the derivation
    of the maximum free convective distance ($d_{clr}$) expected in the pre-aggregated,
    random state. Our goal is to test and further investigate this hypothesis, namely
    that $d_{clr}$ can predict SA occurrence, using an ensemble of twenty-four distinct
    combinations of horizontal mixing, planetary boundary layer (PBL), and microphysical
    parameterizations. We conclude that the key impact of parameterization schemes
    on SA is through their control of the number of convective cores and their relative
    spacing, $d_{clr}$, which itself is impacted by cold-pool (CP) properties and
    mean updraft core size. SA is more likely when the convective core count is small,
    while CPs modify convective spacing via suppression in their interiors and triggering
    by gust-front convergence and collisions. Each parameterization scheme emphasizes
    a different mechanism. Subgrid-scale horizontal turbulent mixing mainly affects
    SA through the determination of convective core size and thus spacing. The sensitivity
    to the microphysics is mainly through rain evaporation and the subsequent impact
    on CPs, while perturbations to the ice cloud microphysics have a limited effect.
    Non-local PBL mixing schemes promote SA primarily by increasing convective inhibition
    through inversion entrainment and altering low cloud amounts, leading to fewer
    convective cores and larger $d_{clr}$. '

  text: Air quality in northern South America faces significant challenges due to
    insufficient high-resolution emission inventories and sparse atmospheric studies.
    This study addresses these gaps by developing a novel framework that integrates
    high-resolution nighttime light data from SDGSAT-1 and multisource remote sensing
    datasets with deep learning techniques to downscale emission inventories. The
    refined inventories are coupled with meteorological inputs into the Weather Research
    and Forecasting (WRF-Chem) model, enabling precise simulation of pollutant dynamics.
    Validated against ground measurements from Colombia's SISAIRE monitoring network,
    demonstrates significant improvements in spatiotemporal accuracy, particularly
    for particulate matter (PM) and nitrogen dioxide (NO₂) with error reductions of
    22–30 % and correlation coefficients increasing from 0.68 to 0.85. These findings
    underscore the critical role of satellite-enhanced inventories in resolving localized
    emission patterns and seasonal variability, such as dry-season PM₁₀ spikes (150
    % increase from wildfires). The framework provides policymakers with actionable
    insights to prioritize mitigation in rapidly urbanizing regions and manage transboundary
    pollution. By bridging data scarcity gaps, this replicable methodology offers
    transformative potential for global air quality management and public health protection,
    advocating for expanded ground monitoring networks and real-time satellite data
    integration in future applications.

  text: In the dynamic arena of innovation, the relations between academia and industry
    are a keystone for breakthroughs and practical applications. Yet, the groundwork
    of these pivotal University-Industry (U-I) partnerships remains covered in complexity.
    This paper delves into these intricate relations, unraveling the factors that
    help successful collaborations. Grounded in the Resource-Based Theory, our study
    transcends traditional analytical boundaries, leveraging a neural network model
    to understand a comprehensive dataset from the UK’s Higher Education Statistics
    Agency, SCIMAGO Rankings, and Clarivate Publications. This novel approach helps
    to make clear the interplay of academic load, administrative support, scientific
    output, and university rank in sculpting U-I collaboration dynamics. Our findings
    suggest that reduced academic load and robust administrative support significantly
    bolster U-I collaborations. However, the influence of scientific output and university
    ranking is more nuanced, challenging the common belief. High scientific output,
    while indicative of expertise, doesn't always align with industry goals. Similarly,
    while higher-ranked universities could attract more collaborations, the benefits
    are not universal. This paper not only contributes to a deeper understanding of
    U-I collaborations, but also provides actionable insights for university administrators,
    policymakers, and industry leaders. In a world where innovation is key, understanding
    these collaborative dynamics is crucial for fostering partnerships that push the
    boundaries of research and practical application.

  text: Wildfire intensity and severity have been increasing in the Iberian Peninsula
    in recent years, particularly in the Galicia region, due to rising temperatures
    and accumulating drier combustible vegetation in unmanaged lands. This leads to
    substantial emissions of air pollutants, notably fine particles (PM2.5), posing
    a risk to public health. This study aims to assess the impact of local and regional
    wildfires on PM2.5 levels in Galicia's main cities and their implications for
    air quality and public health. Over a decade (2013–2022), PM2.5 data during wildfire
    seasons were analyzed using statistical methods and Lagrangian tracking to monitor
    smoke plume evolution. The results reveal a notable increase in PM2.5 concentration
    during the wildfire season (June–November) in Galicia, surpassing health guidelines
    during extreme events and posing a significant health risk to the population.
    Regional wildfire analyses indicate that smoke plumes from Northern Portugal contribute
    to pollution in Galician cities, influencing the seasonality of heightened PM2.5
    levels. During extensive wildfires, elevated PM2.5 concentration values persisted
    for several days, potentially exacerbating health concerns in Galicia. These findings
    underscore the urgency of implementing air pollution prevention and management
    measures in the region, including developing effective alerts for large-scale
    events and improved wildfire management strategies to mitigate their impact on
    air quality in Galician cities.
