Technique Progress and Chemical Mechanism Research of Tropospheric Peroxy Radical in Field Measurement

Peroxy radical chemistry is the main component of tropospheric chemistry, which is critical for the understanding of essential tropospheric issues such as atmospheric cleansing capacity, photochemical ozone production and secondary organic aerosol formations. Field measurements of peroxy radical con...

Description
Summary:Peroxy radical chemistry is the main component of tropospheric chemistry, which is critical for the understanding of essential tropospheric issues such as atmospheric cleansing capacity, photochemical ozone production and secondary organic aerosol formations. Field measurements of peroxy radical concentrations and related analysis with observation based model are the prominent steps to foster the current understanding of peroxy radical chemistry. This paper reviews the state of measurement techniques for peroxy radical, extensively revisits the previous field studies with direct measurements of peroxy radical, outlins the peroxy radical concentrations reported in previous field observations, summarizes the tests of photochemical mechanism with direct field measurement results and discusses the major scientific findings achieved so far. Finally, an outlook for the new directions in the study of atmospheric peroxy radical chemistry is proposed. http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000335279700018&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701 Chemistry, Multidisciplinary SCI(E) 中文核心期刊要目总览(PKU) 中国科技核心期刊(ISTIC) 中国科学引文数据库(CSCD) 2 xytang@pku.edu.cn 4 682-694 26
