At CRISP since December 2022, my focus is on atmospheric chemistry, particularly the study of reactive trace gases using cutting-edge satellite observations and ground-based Pandora spectrometers. Our team's work contributes significantly to understanding urban air quality dynamics. With expertise in atmospheric modeling and a strong background in field measurements, I've honed skills in air quality studies, delving into aerosols and trace gases analysis. Leveraging tools like AERONET and LIDAR, alongside satellite instruments such as the GEMS on the GEO-KOMPSAT-2, enables us to model atmospheric phenomena over South-East Asia with precision. This integrated approach empowers our research, enhancing the oxidative capacity assessments of the atmosphere and providing invaluable insights for environmental policy and public health.
