Sea Spray Aerosol Over the Remote Oceans Has Low Organic Content

Autor: Michael J. Lawler, Gregory P. Schill, Charles A. Brock, Karl D. Froyd, Christina Williamson, Agnieszka Kupc, Daniel M. Murphy

Publikováno v: AGU Advances, Vol 5, Iss 4, Pp n/a-n/a (2024)

Abstract Biogenic organic compounds in the surface ocean may significantly alter the cloud‐forming ability of sea spray aerosol and thereby affect the amount of solar radiation reaching the ocean surface. Estimates of the organic mass fraction of s

Abstract Heterogeneous chemical cycles of pyrogenic nitrogen and halides influence tropospheric ozone and affect the stratosphere during extreme Pyrocumulonimbus (PyroCB) events. We report field‐derived N2O5 uptake coefficients, γ(N2O5), and ClNO2

Global distribution of Asian, Middle Eastern, and North African dust simulated by CESM1/CARMA

Autor: Siying Lian, Luxi Zhou, Daniel M. Murphy, Karl D. Froyd, Owen B. Toon, Pengfei Yu

Publikováno v: Atmospheric Chemistry and Physics. 22:13659-13676

Dust aerosols affect the radiative and energy balance at local and global scales by scattering and absorbing sunlight and infrared light. A previous study suggests that dust size distribution is one of the major sources of uncertainty in modeling the

Identifying chemical aerosol signatures using optical suborbital observations: how much can optical properties tell us about aerosol composition?

Publikováno v: Atmospheric Chemistry and Physics. 22:3713-3742

Improvements in air quality and Earth’s climate predictions require improvements of the aerosol speciation in chemical transport models, using observational constraints. Aerosol speciation (e.g., organic aerosols, black carbon, sulfate, nitrate, am
