Topic:Vertical Distribution of Aerosols from Surface to Low Stratosphere over East Asia: Balloon and Aircraft Measurements

Date:2017.9.13 10:00-11:30

Location:Room S-818, Meng Minwei Science & Technology Building

Presenter:Daizhou Zhang  Prefectural University of Kumamoto, Japan

Abstract

The purpose of this talk is to provide a primary understanding on the distribution of aerosol particles in vertical direction in the atmosphere over East Asia. First, some fundamental knowledge on the thermodynamic structure of near surface air will be briefly introduced. Then, two case data: one on the aerosols in a convective mixing layer in Beijing from a tethered balloon mission, and another on the aerosols from surface to low troposphere from aircraft missions,will be introduced in details. Finally, some results on aerosols in free troposphere and low stratosphere from balloon sonde missions will be presented. 

Presenter Profile

Dr. Daizhou Zhang is a professor in the Faculty of Environmental and Symbiotic Sciences of the Prefectural University of Kumamoto, Japan.He studied in Peking University from 1983 to 1994, and worked there as a postdoc and a staff before he started to work in the present university in 1999. After getting his degree by a study of internal gravity waves in the low tropical stratosphere at Peking University, he turned to study atmospheric aerosols. He has been working on aerosol particles at various areasfrom Chinese deserts to the Northwestern Pacific, and trying to reveal and elucidate the physical and chemical properties and their variations during the long-distance transport over East Asia. Recently, he has extended his research interests to bacterial aerosols and their dependence on mineral particles and weather conditions. (Lab homepagehttp://www.pu-kumamoto.ac.jp/~aerl/)
