Kuala Lumpur 2019 Summary

Fourth Workshop on Atmospheric Composition and the Asian Monsoon (ACAM)

26-28 June 2019

Universiti Kebangsan Malaysia (UKM), Bangi,  Selangor, Malaysia


Background

IGAC sponsored this workshop to support the joint IGAC/SPARC activity ACAM (Atmospheric Composition and the Asian Monsoon), which aims to build strong international collaborations to obtain diverse expertise and resources for ACAM science, and access to the monsoon region for international research teams.

The 4th ACAM Workshop was held at the Universiti Kebangsaan Malaysia (UKM) in Bangi, Selangor, Malaysia, 26-28 June 2019, including 153 participants from 22 countries/regions. The overall aim of the workshop was to exchange information on the latest results in the very interdisciplinary field of ACAM science and to foster international collaborations in the Asian region and worldwide. Scientific presentations and discussions covered a broad range of topics including air quality, monsoon convection coupled to surface emissions, transport pathways of pollutants into the stratosphere, Asian tropopause aerosol layer (ATAL), and monsoon-climate interactions. Emissions in the Asian monsoon region are still increasing due to rapid population and economic growth, thus, accurate representation of the monsoon system in global chemistry-climate models is critical to predicting climate change.
 
The workshop program was structured according to the four ACAM themes 1) Emissions and air quality in the Asian monsoon region, 2) Aerosols, clouds, and their interactions with the Asian monsoon, 3) Impact of monsoon convection on chemistry, 4) Response of the upper troposphere and lower stratosphere to the Asian Monsoon. The workshop included 50 oral and 90 poster presentations. All posters were also introduced in rounds of 1-minute oral presentations. Each session began with scene setting invited talks. Results from recent aircraft and balloon campaigns were presented including StratoClim, BATAL, and SWOP. Modelling results discussed covered processes coupling local emissions with regional and global composition and climate, and satellite retrievals of atmospheric composition over the Asian monsoon region were presented. In addition, plans for upcoming field campaigns related to ACAM were reported, e.g. the ACCLIP campaign in 2020. Most of the oral and poster presentations will be available on the ACAM website.

The workshop included also break-out meetings of the three ACAM working groups 1) “Observations and Data Sharing” which aims to identify ACAM-relevant datasets, organize data sharing, and encourage future coordinated observations, 2) “Modeling and Analysis” with the objective to foster interactions between the global and regional modeling communities and to organize ACAM-related modeling and analysis, 3) “Training School” which is focusing on the development of future training opportunities for early career scientists on observations and modeling. In the working group meetings the focus of the discussions was on the best way to promote collaborations in the field of ACAM science, e.g. partnership with other modeling communities (e.g. CCMI, AEROCAM) and sharing of data from recent ACAM-related field campaigns. The outcome of the working group meetings were summarized in plenum presentations. 

This was the fourth ACAM workshop following the workshops in Kathmandu, Nepal in 2013, Bangkok, Thailand in 2015, and Guangzhou, China in 2017, and provided again an excellent opportunity for ACAM scientists, in particular early career scientists, to highlight their research results. About 30 percent of the oral presentations were given by early career scientists. The discussions during the extended poster sessions and working group meetings allowed the scientists to initiate and strengthen collaborations with international partners.
