Atmospheric Oxidation Nexus — From Emissions to Impacts
I trace how the atmosphere’s cleaning power connects human activities, extreme‑weather triggers, and Earth‑system feedbacks. Specifically, I study how anthropogenic actions and a warming climate reshape the atmospheric oxidising capacity (OH/HO2, O3)—and how those shifts feed back to climate, weather events (e.g., sea fog), ecosystems, and human health. My research spans the full chain from Emission → Chemical Transformation → Weather / Climate Coupling to Feedbacks on Climate, Weather & Life.
- 🌇⛽️Anthropogenic Emission Fingerprints: Characterise and quantify anthropogenic VOC / HONO fingerprints across diverse emission sectors.
- 🧊💥Chemical Mechanisms Shaping Atmospheric Oxidising Capacity: Dissect chemical networks, identify missing sinks of free radicals, and benchmark chemical mechanisms.
- 🌕💨Weather–Climate Modulation of Atmospheric Oxidation: Diagnose how heatwaves, boundary‑layer dynamics, sea‑breeze systems, etc. interact with chemistry and transport, altering pollutant loads.
- 🌁🌲Oxidant‑Driven Feedbacks on Climate, Weather & Life: Link source–chemistry–weather interactions to climate feedbacks, specific weather events (e.g., sea fog), and ecosystem or health outcomes.
