Spectro-microscopic analysis of soot particle composition and source attribution

Felipe Rivera-Adorno, Steven Sharpe, Temitope Olayemi, Julius Iruoghene Ese et autres

Ambient soot particles significantly impact Earth’s radiative balance, human health, and atmospheric visibility. Their microstructural properties depend on formation and aging mechanisms, which vary by emission source and atmospheric processes. Hence, accurately identifying sources of soot enhances our understanding of their physicochemical …

Investigating New Particle Formation and Growth Over an Urban Location in the Eastern Mediterranean

T. C. Ajith, Eli Windwer, Chunlin Li, Zheng Fang et autres

Abstract This study investigates the new particle formation (NPF) events at an urban location in the Eastern Mediterranean. Particle size distribution, particulate chemical composition, and gaseous pollutants were monitored in Rehovot, Israel (31°53″N 34°48″E) during two campaigns: from April 29 to 3 …

Evolution of Organic Aerosols in the South Asian Outflow to the Northern Indian Ocean

T. C. Ajith, Sobhan Kumar Kompalli, Vijayakumar S. Nair, Mukunda M. Gogoi et autres

The chemical composition of the nonrefractory submicron aerosols (NR-PM 1.0 ) in the South Asian outflow to the northern Indian Ocean (NIO) during winter was examined as part of the Integrated Campaign for Aerosols, gases, and Radiation Budget (ICARB-2018) ship-based experiment with …

Chemical characterization of aerosols in the South Asian outflow over the northern Indian Ocean: latitudinal gradients and ultrafine particle events

Vijayakumar S. Nair, S. Suresh Babu, Sobhan Kumar Kompalli, V. Jayachandran et autres

Changes in the chemical properties of aerosols in the South Asian outflow to the northern Indian Ocean during winter are examined. The mass loading of organic aerosols increase during ultrafine particle events and decrease rapidly with distance from the coast.

Role of Aerosol Physicochemical Properties on Aerosol Hygroscopicity and Cloud Condensation Nuclei Activity in a Tropical Coastal Atmosphere

T. C. Ajith, Sobhan Kumar Kompalli, S. Suresh Babu

Simultaneous measurements of cloud condensation nuclei (CCN) number concentration (between 0.20 and 1% supersaturation), particle number size distributions (PNSDs, 9.8 to 414 nm), and nonrefractory submicron aerosol (NR-PM 1.0 ) chemical composition were carried out from a tropical coastal location Thumba, in …
