Bounding Global Aerosol Radiative Forcing of Climate Change

open access: yesReviews of Geophysics, 2020
Aerosols interact with radiation and clouds. Substantial progress made over the past 40 years in observing, understanding, and modeling these processes helped quantify the imbalance in the Earth's radiation budget caused by anthropogenic aerosols, called

Aerosol and monsoon climate interactions over Asia

open access: yesReviews of Geophysics, 2016
The increasing severity of droughts/floods and worsening air quality from increasing aerosols in Asia monsoon regions are the two gravest threats facing over 60% of the world population living in Asian monsoon regions.

Aerosol Mixing State: Measurements, Modeling, and Impacts

open access: yesReviews of Geophysics, 2019
Atmospheric aerosols are complex mixtures of different chemical species, and individual particles exist in many different shapes and morphologies. Together, these characteristics contribute to the aerosol mixing state. This review provides an overview of

Source apportionment of black carbon and combustion-related CO2 for the determination of source-specific emission factors [PDF]

open access: yesAtmospheric Measurement Techniques, 2023
Black carbon (BC) aerosol typically has two major sources in the urban environment: traffic and domestic biomass burning, which has a significant contribution to urban air pollution during the heating season. Traffic emissions have been widely studied by

Highly Time-Resolved Apportionment of Carbonaceous Aerosols from Wildfire Using the TC–BC Method: Camp Fire 2018 Case Study

open access: yesToxics, 2023
The Camp Fire was one of California’s deadliest and most destructive wildfires, and its widespread smoke threatened human health over a large area in Northern California in November 2018.

Rapid measurement of RH-dependent aerosol hygroscopic growth using a humidity-controlled fast integrated mobility spectrometer (HFIMS) [PDF]

open access: yesAtmospheric Measurement Techniques, 2021
The ability of aerosol particles to uptake water (hygroscopic growth) is an important determinant of aerosol optical properties and radiative effects.

Regularized inversion of aerosol hygroscopic growth factor probability density function: application to humidity-controlled fast integrated mobility spectrometer measurements [PDF]

open access: yesAtmospheric Measurement Techniques, 2022
The new Aerosol hygroscopic growth plays an important role in atmospheric particle chemistry and the effects of aerosol on radiation and hence climate. The hygroscopic growth is often characterized by a growth factor probability density function (GF-PDF),

Molecular rearrangement of bicyclic peroxy radicals is a key route to aerosol from aromatics

open access: yesNature Communications, 2023
The oxidation of aromatics contributes significantly to the formation of atmospheric aerosol. Using toluene as an example, we demonstrate the existence of a molecular rearrangement channel in the oxidation mechanism.
