A consultancy project funded by EPD

Dr. Lyu is awarded a consultancy project with a total funding of HK$1,200,000 by Hong Kong Environmental Protection Department. This project entitled 'Feedback Mechanism of Secondary Reactive Gases Generated in Photochemical Smog to Ozone Formation  and Regional Photochemistry' aims to i) characterize the temporal evolutions of HONO and HCHO in O₃ pollution periods in urban HK; ii) determine the dynamic fractions of secondary HONO and HCHO utilizing a combination of observational and modelling approaches; iii) unravel the feedbacks of secondary reactive gases to O₃ formation and regional photochemistry; and iv) explore innovative strategies of O₃ pollution control from the perspective of mediating the feedback effect.
