The Asian Summer Monsoon Chemical and Climate Impact Project (ACCLIP): An Overview

Le résumé fourni par la source

Abstract The Asian summer monsoon Chemical and Climate Impact Project is centered on a large airborne field campaign investigating the role the Asian Summer Monsoon (ASM) plays in changing the atmospheric composition in the upper troposphere and lower stratosphere. This campaign, conducted in Summer 2022 using two research aircraft, has obtained the most comprehensive data set for chemical composition, including hundreds of trace gas species as well as the physical and chemical properties of aerosols in the ASM convective outflow over East Asia and the Western Pacific. These data show that the ASM deep convection is creating a chemically distinct layer near the tropopause that has large anthropogenic influences. This overview provides a summary of the project, including the scientific objectives, dynamical, and meteorological conditions of the campaign season, key elements of the campaign operations, selected scientific highlights, and ongoing research.
