Liu, X., Huang, Y., Chen, Y., Feng, X., Li, J., et al. (2025). Abundance of volatile organic compounds and their role in ozone pollution management: evidence from multi-platform observations and model representation during the 2021–2022 field campaign in Hong Kong. Atmospheric Chemistry and Physics, doi:https://doi.org/10.5194/acp-25-17629-2025 Abstract. Volatile organic compounds (VOCs) are a diverse group of species that contribute to ozone formation. However, our understanding of VOC dynamics and their effect on ozone pollution is limited by the lack of long-term, continuous, a...

Tomazzeli, O. G., Palancar, G., Minschwaner, K., Ji, A., Madronich, S., et al. (2025). Impact of the overlapping O2 Schumann-Runge and Herzberg continua with Schumann-Runge bands on photolysis rate coefficients: comparing the Koppers & Murtagh parameterization with line-by-line cross section. Journal of Quantitative Spectroscopy and Radiative Transfer, doi:https://doi.org/10.1016/j.jqsrt.2025.109678 In this study, we update and integrate a line-by-line (LBL) module for calculating the O2 cross section (σO2) within the Schumann-Runge Bands (SRB, 175.4-206.2 nm) into the Tropospheric Ultraviolet Visible (TUV) model V5.4. This coupling al... ACOM Affiliations: ESS Publication Genre: Article View on OpenSky |

Landscape fire emissions from the 5th version of the Global Fire Emissions Database (GFED5) Werf, G. R. v. d., Randerson, J. T., Wees, D. v., Chen, Y., Giglio, L., et al. (2025). Landscape fire emissions from the 5th version of the Global Fire Emissions Database (GFED5). Scientific Data, doi:https://doi.org/10.1038/s41597-025-06127-w Landscape fires are a major source of greenhouse gases and other atmospheric constituents. Most global inventories of landscape fire emissions have converged at around 2 petagram of carbon (Pg C) y−1 since satellite information on burned ar...

Investigating fire-induced ozone production from local to global scales Palmo, J. O., Heald, C. L., Blake, D. R., Bourgeois, I., Coggon, M., et al. (2025). Investigating fire-induced ozone production from local to global scales. Atmospheric Chemistry and Physics, doi:https://doi.org/10.5194/acp-25-17107-2025 Abstract. Tropospheric ozone (O3) production from wildfires is highly uncertain; previous studies have identified both production and loss of O3 in fire-influenced air masses. To capture the total ozone production attributable to a smoke pl... ACOM Affiliations: ESS Publication Genre: Article View on OpenSky |

Dust direct radiative effect including large particles and component minerals Li, L., Mahowald, N. M., Obiso, V., Kok, J. F., Miller, R. L., et al. (2025). Dust direct radiative effect including large particles and component minerals. Geophysical Research Letters, doi:https://doi.org/10.1029/2025gl119383 The direct radiative effect (DRE) of dust aerosols in Earth system models (ESMs) remains highly uncertain, largely due to inadequate representations of particle size distribution (PSD) and mineral composition. Using NASA's Earth Surface Min... ACOM Affiliations: MODELING Publication Genre: Article View on OpenSky |
