Chiral Volatile Organic Compound Fluxes from Soil in the Amazon Rainforest across seasons Open
The rainforest floor is an underexplored source and sink of biogenic volatile organic compounds (BVOC), and its contribution to the ecosystem BVOC budget remains poorly understood. We performed multi-seasonal measurements in the Amazon rai…

Enhancement of O <sub>3</sub> –CO ratios at tropospheric subtropical latitudes: Photochemistry and stratospheric influence Open
The subtropics are influenced by stratosphere-troposphere exchange processes through the subtropical jet streams and tropopause folding events, which are commonly identified by the opposing gradients of ozone (O3) and carbon monoxide (CO) …

Equatorial upwelling of phosphorus drives Atlantic N2 fixation and Sargassum blooms Open
The Great Atlantic Sargassum Belt first appeared in 2011 and quickly became the largest interconnected floating biome on Earth. In recent years, Sargassum stranding events have caused substantial ecological and socio-economic impacts in co…

Global impact of anthropogenic NH <sub>3</sub> emissions on upper tropospheric aerosol formation Open
Anthropogenic ammonia (NH 3 ) emissions have significantly increased in recent decades due to enhanced agricultural activities, contributing to global air pollution. While the effects of NH 3 on surface air quality are well documented, its…

Avoided mortality by particulate air pollution control measures in China Open
Since 2006, China has undertaken essential efforts to reverse the sharp atmospheric pollution increase, especially to reduce fine particulate matter with a diameter smaller than 2.5 μm (PM2.5). Using satellite observations, we d…

The influence of ammonia emission inventories on size-resolved global atmospheric aerosol composition and acidity Open
Ammonia (NH3) is an abundant alkaline gas in the atmosphere and a key precursor in the formation of particulate matter. While emissions of other aerosol precursors such as SO2 and NOx have decreased significantly, global NH3 emissions are …

Changes in global atmospheric oxidant chemistry from land cover conversion Open
Human activities have profoundly altered natural vegetation, primarily by converting pristine natural land to agriculture and grazing. Land cover change (LCC) influences the Earth system through modifications of surface albedo, roughness l…

Mirror image molecules expose state of rainforest stress Open
Monoterpenes are key to plant communication and defence against biotic (e.g., herbivory) and abiotic (e.g., heat, drought) stress. Chiral monoterpenes, like alpha-pinene, exist as mirror image pairs, known as enantiomers. Enantiomers have …

A comprehensive review/expert statement on environmental risk factors of cardiovascular disease Open
Cardiovascular disease (CVD) is the leading cause of mortality globally, with over 20 million deaths each year. While traditional risk factors—such as hypertension, diabetes, smoking, and poor diet—are well-established, emerging evidence u…

Radiative forcing and stratospheric ozone changes due to major forest fires and recent volcanic eruptions including Hunga Tonga Open
Recent studies suggest that emissions from large forest fires affect stratospheric chemistry, dynamics, and climate, similar to major volcanic eruptions. Using the chemistry-climate model EMAC, we demonstrate that organic carbon emitted fr…

Guidelines for Modeling and Reporting Health Effects of Climate Change Mitigation Actions Open
BACKGROUND: Modeling suggests that climate change mitigation actions can have substantial human health benefits that accrue quickly and locally. Documenting the benefits can help drive more ambitious and health-protective climate change mi…

Short-lived organic nitrates in a suburban temperate forest: an indication of efficient assimilation of reactive nitrogen by the biosphere? Open
Alkyl nitrates (ANs) and peroxycarboxylic nitric anhydrides (PANs) are important reservoirs of reactive nitrogen that contribute significantly to the rate of formation and growth of secondary organic aerosols and support the transport of r…

Mirror image molecules expose state of rainforest stress Open
Monoterpenes (C10H16) serve as a vital medium for plant communication and defence against biotic (e.g., herbivory) and abiotic (e.g., heat and drought) stresses[1-6]. Some monoterpenes, such as alpha-pinene, are chira…

Impacts of convection, chemistry, and forest clearing on biogenic volatile organic compounds over the Amazon Open
The Amazon rainforest is the largest source of biogenic volatile organic compounds (BVOCs) to the atmosphere. To understand the distribution and chemistry of BVOCs, airborne and ground-based measurements of BVOCs are conducted over the Ama…
