Marine aerosol feedback on biogeochemical cycles and the climate in the Anthropocene: lessons learned from the Pacific Ocean
Marine aerosol feedback on biogeochemical cycles and the climate remains highly uncertain due to the complex interplay. This review highlights recent advances in our understanding of organic aerosols, nitrogen, and iron as well as cloud properties over the Pacific Ocean.

Terrestrial carbon cycle: tipping edge of climate change between the atmosphere and biosphere ecosystems
Being a climate change nexus, the study on the carbon cycle depicts the existence of its mechanistic link with the atmospheric and biospheric environment.
Paper
Evaluating reduced-form modeling tools for simulating ozone and PM2.5 monetized health impacts
Reduced-form modeling approaches are an increasingly popular way to rapidly estimate air quality and human health impacts related to changes in air pollutant emissions.
Paper
Negligible increase in indoor endotoxin activity by 222 nm far-UVC illumination on bioaerosols
Far-UVC irradiation (222 nm) is an emerging approach for disinfection due to its effectiveness and potentially harmless nature to humans by direct irradiation compared with other UV wavelengths.
Paper
Influence of ambient and endogenous H2O2 on reactive oxygen species concentrations and OH radical production in the respiratory tract
A multiphase kinetic model analysis quantifies effects of air pollutants on reactive oxygen species production and oxidative stress in the respiratory tract.
Paper
Composition, concentration, and oxidant reactivity of sesquiterpenes in the southeastern U.S.
Sesquiterpene composition at two sites representative of the southeastern U.S. is similar with β-caryophyllene and humulene dominating ozone reactivity.
Paper
Emission of primary bioaerosol particles from Baltic seawater
Bioaerosols within sea spray are particles of biological origin with various important atmospheric implications. These particles were characterized here using novel single-particle spectroscopy and microbial community composition analysis.
Paper
Analysis of the effect of abiotic stressors on BVOC emissions from urban green infrastructure in northern Germany
Drought stress was identified as the most important abiotic stressor that modulates emissions of biogenic volatile compounds in a Northern European city. Isoprene concentrations were reduced by 65% under drought stress during the growing period compared to non-stress conditions.
Paper
Changes to lung surfactant monolayers upon exposure to gas phase ozone observed using X-ray and neutron reflectivity
Lung surfactant at the air water interface reacts with ozone leading to changes in surface tension, film thickness, structure.
Paper
Seasonality of isoprene emissions and oxidation products above the remote Amazon
The Amazon rainforest is the largest source of isoprene emissions to the atmosphere globally.
Paper
Atmospheric inputs of volcanic iron around Heard and McDonald Islands, Southern ocean
Increased atmospheric Fe loading and solubility was attributed to emissions from Heard Island volcano (Kerguelen plateau), emphasizing the need for models to consider volcanoes as a source of aeolian Fe to remote oceanic regions.
About this collection
This collection highlights leading research published in Environmental Science: Atmosphereswhich studies the relationships and interactions between the Earth's atmosphere and its living organisms. Topics covered include biogeochemical cycling of gases between the atmosphere and biosphere, the impacts of human activities on atmosphere-biosphere interactions and climate patterns, and how air quality impacts the wellbeing of humans, animals, and plants.
