Mathew Sebastian, Ph D student from the Centre for Earth, Ocean and Atmospheric Sciences, School of Physics, University of Hyderabad, working under the supervision of Dr. Vijay Kanawade, presented a paper titled “Characteritics of size-segregated particle concentrations in an urban location in India” at the European Geophysical Union (EGU) General Assembly 2023 in Vienna, Austria.

Mathew’s paper presents critical analyses of 3-year long in-situ measurements of aerosols (solid or liquid particles suspended in the air) from the University of Hyderabad campus site. Mathew and his co-worker characterized size-segregated aerosol number and mass concentrations. They found strong temporal variability in size-segregated particle number and mass concentrations, which has implications for air quality, weather, and climate studies. While the smaller size (cluster mode) particles contributed the most to aerosol numbers, the bigger particles (Aitken and accumulation mode particles) contributed the most to aerosol mass.

This work is part of his doctoral study, which focuses on the improved understanding of new particle formation and growth in diverse environments in India.

The EGU General Assembly 2023 brings together geoscientists from all over the world to one meeting covering all disciplines of the Earth, planetary, and space sciences. The EGU aims to provide a forum where scientists, especially early career researchers, can present their work and discuss their ideas with experts in all fields of geoscience.

Mathew’s attendance at the conference was made possible through partial funding from the Institution of Eminence (IoE) travel grant scheme and the Science Engineering Research Board – International Travel Scheme (SERB-ITS). Mathew also acknowledges the Junior Research Fellowship from the Institution of Eminence (IoE) to carry out his doctoral work at the University of Hyderabad. Mathew is in the fifth year of his Ph.D. and he has published 3 first-authored and 2 co-authored articles in highly reputed Journals including Geophysical Research-Atmospheres and Atmospheric Chemistry and Physics.
