Title: Air Pollution-Observational Constraints in Relative Contributions from Transport in Relative Contributions from Transport vs Local Production and Their Scientific Limitations


Abstract:

It is fair to say that most of the Korean citizens are eager to know exact contributions from regional

transport in their air pollution problems in one number. In the seminar, we will discuss that it is an

impossible to do. More importantly, a key uncertainty will be highlighted surrounding constraining

reactive gas precursors in the air producing aerosols and ozone through photochemical processes.

We will particularly discuss about observational constraints quantified during the KORUS-AQ campaign

in 2016. The particular uncertainties we have identified are 1) substantial unknown reactive gases over

the surface of the Seoul suburban area and 2) rapid oxidation of the reactive gases over the surface.

We will discuss their implication towards assessing relative pollution contributions from local and transport.

Finally, the new airborne observation research initiative will be introduced to improve our understanding

in trace gas distributions that eventually empowering the modeling capacity and the satellite data retrieval processes.
