Key drivers of the oxidative potential of PM2.5 in Beijing in the context of air quality improvement from 2018 to 2022

Environment International
The mass concentration of atmospheric particulate matter (PM) has been continuously decreasing in the Beijing-Tianjin-Hebei region. However, health endpoints do not exhibit a linear correlation with PM mass concentrations.

Evaluation of different sampling methods to determine the ice-nucleating particle concentration in the atmosphere using the GRAnada Ice Nuclei Spectrometer (GRAINS) [PDF]

Atmospheric Measurement Techniques
This work deals with the analysis of different filter sampling methods to obtain INP concentration spectra using the GRAnada Ice Nuclei Spectrometer (GRAINS), a droplet freezing array based on the design of the Colorado State University Ice Spectrometer (

An observation-constrained estimation of brown carbon aerosol direct radiative effects [PDF]

Atmospheric Chemistry and Physics
Brown carbon (BrC) is an organic carbon component with noticeable absorption in the ultraviolet and short visible wavelengths, which influences the global radiative balance. However, assessing BrC radiative effects remains a challenging task owing to the

Concentration and source changes of nitrous acid (HONO) during the COVID-19 lockdown in Beijing [PDF]

Atmospheric Chemistry and Physics
Nitrous acid (HONO) is an important precursor of OH radicals which affects not only the sinks of primary air pollutants but also the formation of secondary air pollutants, but its source closure in the atmosphere is still controversial due to a lack of ...

Pathway-dependent thermodynamic adjustment shapes cold-advection low-cloud regimes over the Eastern North Atlantic

Environmental Research Letters
Marine low clouds strongly affect Earth’s radiation budget, yet climate models continue to underestimate shallow cumulus and misrepresent low-cloud regimes in cold-advection environments.

Improving precipitation simulations in CIESM through a new entrainment rate parameterization

npj Climate and Atmospheric Science
Entrainment rate parameterization is important for convection schemes but uncertain in climate models. A new deep convective entrainment rate (λ) parameterization (HL parameterization) is developed from aircraft observations and implemented into the ...
