The main focus of the Atmospheric Photochemistry Research Group at GIGChinese Academy of Sciences is to understand and quantify the photochemical processes occurring on various surfaces of atmospheric relevance and within the aerosol deliquescent particles. This research is critical because provides quantitative information that can be used in photochemical models (regional and global scale) to better understand the air quality and climate change issues.

 

 

The current research projects: 

 

 

The photochemical processes occurring at the air-sea interface

 

 

A detailed knowledge of the photochemical interactions between the gas-phase and the sea-surface microlayer is indispensable in order to understand the air quality and global climate phenomena.

 

 

Light-induced heterogeneous chemistry on urban grime

 

 

A comprehensive knowledge about the photochemical processes on the urban surfaces and their impact on the air quality is both crucial and urgent. This project lay the necessary foundations and represents significant advances toward reaching this vital goal.

 

 

The photochemical reactions in the aqueous phase (fog, rain, aerosol deliquescent particles)

 

 

There is increasing evidence that aqueous-phase atmospheric photochemistry is an important source of secondary organic aerosols (SOA), but the related processes are currently not adequately represented in atmospheric chemistry models.

 

 

Indoor Atmospheric Chemistry: An Emerging Global Concern

 

 

People increasingly live indoors as societies industrialize, but the (photo)chemistry that determines our indoor pollutant exposure is not fully understood.
