6B: Atmospheric Composition and the Asian Monsoon (ACAM) Workshop

With rapid population and economic growth across the Asian monsoon region, it becomes a pressing concern that the monsoon dynamics coupled to surface emissions is playing a significant role in chemistry-climate interactions and connecting the climate change with the region’s air quality. The uplift of pollutants also enhances aerosol–cloud interactions that may change the behavior of the monsoon. The chemical transport effect of the monsoon system is seen from satellites as an effective transport path for pollutants to enter the stratosphere. The monsoon system is therefore relevant to scales and processes bridging regional air quality, climate change, and global chemistry-climate interaction. Accurate representation of this system in global chemistry-climate models is critical to predicting how this evolving region may contribute to future change. To characterize and quantify the impact of the system, integrated study is essential, including observations (in situ and remote sensing) from the surface through the troposphere and stratosphere as well as modeling from regional to global scales. To be successful in this pursuit, it is necessary to build strong international collaborations to obtain the diverse expertise, resources, and access to the monsoon region for international research teams.

The international activity, Atmospheric Composition and the Asian Monsoon (ACAM), represents a critical step in building these international relationships. ACAM has been an activity jointly sponsored by the SPARC (Stratosphere-troposphere Processes And their Role in Climate, a core project under WMO/WCRP), and IGAC (International Global Atmospheric Chemistry) since 2015. The activity organizes biannual workshops that create a crossroads for regional and international researchers to meet and identify shared scientific interests surrounding the Asian monsoon and atmospheric composition. Fostering collaboration and capacity building is an important part of the ACAM activity.  Training schools are organized to specifically address the need for monsoon region’s students and early career scientists to gain access to satellite and airborne data, and to connect with advanced global models. NCAR ACOM scientists serve in leadership roles in the ACAM scientific steering group.

During June 2017, ACAM held its third international workshop, followed by its second training school in Jinan University, Guangzhou China. The workshop is participated by 160 scientists from 19 countries, including 12 Asian countries, and include a significant fraction of early career scientists. The training school, themed Observations and Modeling of Atmospheric Chemistry and Aerosols in the Asian Monsoon, was attended by over 40 students and supported by 9 lecturers, represented 7 Asian countries and 3 European countries. ACOM scientists co-chaired the workshop and the training school, and taught in the training school. Please see 2nd Atmospheric Composition and the Asian Monsoon (ACAM) Training School – Observations and Modeling of Atmospheric Chemistry and Aerosols in the Asian Monsoon Region for more information.

The workshop and the training school were enabled by generous sponsorship from the following organizations that provided for meeting facilities and expenses as well as travel support for 55 of the meeting attendees: China Association for Science and Technology (CAST), Chinese Academy of Sciences (CAS), Key Laboratory of Middle Atmosphere and Global Environment Observation (LAGEO), Nanjing University of Information Science and Technology (NUIST), Jinan University, International Commission on Atmospheric Chemistry and Global Pollution (iCACGP), Stratosphere-troposphere Processes And their Role in Climate (SPARC), International Global Atmospheric Chemistry project (IGAC), International Centre for Integrated Mountain Development (ICIMOD), Forschungszentrum Jülich, National Center for Atmospheric Research (NCAR), National Aeronautics and Space Administration (NASA), and Picarro Inc. Both the workshop and the training school significantly benefitted from the outstanding support from local student volunteers at Jinan University. The highlight of these events are published in SPARC and IGAC newsletters.
