Autor: Jonathan M. Moch, Loretta J. Mickley, Sebastian D. Eastham, Elizabeth W. Lundgren, Viral Shah, Jonathan J. Buonocore, Jacky Y. S. Pang, Mehliyar Sadiq, Amos P. K. Tai

Publikováno v: AGU Advances, Vol 4, Iss 5, Pp n/a-n/a (2023)

Abstract Studies of the impacts of solar geoengineering have mostly ignored tropospheric chemistry. By decreasing the sunlight reaching Earth's surface, geoengineering may help mitigate anthropogenic climate change, but changing sunlight also alters

Control of particulate nitrate air pollution in China

Publikováno v: Nature Geoscience. 14:389-395

The concentration of fine particulate matter (PM2.5) across China has decreased by 30–50% over the period 2013–2018 due to stringent emission controls. However, the nitrate component of PM2.5 has not responded effectively to decreasing emissions

Aerosol‐Radiation Interactions in China in Winter: Competing Effects of Reduced Shortwave Radiation and Cloud‐Snowfall‐Albedo Feedbacks Under Rapidly Changing Emissions

Autor: Jonathan M. Moch, Loretta J. Mickley, Christoph A. Keller, Huisheng Bian, Elizabeth W. Lundgren, Shixian Zhai, Daniel J. Jacob

Publikováno v: Journal of Geophysical Research: Atmospheres. 127

Since 2013, Chinese policies have dramatically reduced emissions of particulates and their gas-phase precursors, but the implications of these reductions for aerosol-radiation interactions are unknown. Using a global, coupled chemistry-climate model,

Further improvement of wet process treatments in GEOS-Chem v12.6.0: impact on global distributions of aerosols and aerosol precursors

Autor: Fangqun Yu, Jonathan M. Moch, Gan Luo

Publikováno v: Geoscientific Model Development, Vol 13, Pp 2879-2903 (2020)

Wet processes, including aqueous-phase chemistry, wet scavenging, and wet surface uptake during dry deposition, are important for global modeling of aerosols and aerosol precursors. In this study, we improve the treatments of these wet processes in t

Stratospheric aerosol injection may impact global systems and human health outcomes

Autor: Samantha M. Tracy, Jonathan M. Moch, Sebastian D. Eastham, Jonathan J. Buonocore

Publikováno v: Elementa: Science of the Anthropocene. 10

Solar radiation management (SRM) is a climate engineering strategy to reduce temperature increases due to global climate change. The most well-researched SRM methodology is stratospheric aerosol injection (SAI), which involves increasing the concentr

Catalytic role of formaldehyde in particulate matter formation

Autor: Eleni Dovrou, Kelvin H. Bates, Jonathan M. Moch, Loretta J. Mickley, Daniel J. Jacob, Frank N. Keutsch

Publikováno v: Proceedings of the National Academy of Sciences of the United States of America. 119(6)

Significance Particulate matter, often formed via cloud processing, strongly influences the Earth’s climate and air quality. Particle composition depends on anthropogenic and biogenic emissions. Thus, in order to understand climate change, knowledg

Interpretation of geostationary satellite aerosol optical depth (AOD) over East Asia in relation to fine particulate matter (PM2.5): insights from the KORUS-AQ aircraft campaign and seasonality

Geostationary satellite sensors over East Asia (GOCI and AHI) are now providing continuous mapping of aerosol optical depth (AOD) at 550 nm to improve monitoring of fine particulate matter (PM2.5) air quality. Here we evaluate our understanding of

Sulfur compounds are an important constituent of particulate matter, with impacts on climate and public health. While most sulfur observed in particulate matter has been assumed to be sulfate, laboratory experiments reveal that hydroxymethanesulfonat

Global modeling of cloudwater acidity, rainwater acidity, and acid inputs to ecosystems

Autor: Jonathan M. Moch, Daniel J. Jacob, Viral Shah, Shixian Zhai, Xuan Wang

Cloudwater acidity affects the atmospheric chemistry of sulfate and organic aerosol formation, halogen radical cycling, and trace metal speciation. Rainwater acidity including post-depositional inputs adversely affects soil and freshwater ecosystems.
