The 6th ACAM workshop: June 11-13, & the 6th ACAM training school: June 9-10 , 2025 Bali, Indonesia.

In June 2025, the ACAM community will gather in Bali, Indonesia for its 6th biennial workshop and training school. Since the first ACAM workshop in 2013 in Kathmandu, ACAM events have been held at locations across the Asian monsoon region, including Thailand, China, Malaysia, and Bangladesh. Over this period, ACAM has promoted close coordination across satellite observations, field campaigns, and modeling to better understand and characterize the interactions between atmospheric composition and the Asian monsoon. The couplings and feedbacks between emissions, pollution transport, and the Asian monsoon circulation span the region from the surface to the upper troposphere/lower stratosphere (UTLS). The breadth of these connections has attracted a community with equally broad expertise, and the resulting collaborations have been an important outcome of ACAM workshops. Collaborations within the ACAM community over the past decade have led to multiple synergistic activities across Asia in the form of intensive field campaigns, modeling activities, and coordinated synthesis of measurements towards an improved understanding of monsoon-related processes.

The 2025 ACAM workshop will once again provide a strong scientific forum for exchange on the latest research and activities related to aerosols and air quality, ambient air pollutant and greenhouse gas fluxes, chemistry-climate modeling, UTLS transport, and monsoon coupling processes. The upcoming ACAM event will also include specific sessions to reflect on the accomplishments of the ACAM community over the last decade, summarize what we have learned, and identify the key scientific challenges and opportunities that lie ahead. Integration of satellite data, burgeoning ground networks, models, and field observations has emerged as one of the key frameworks to study ACAM-relevant topics, which are expected to become even more important in future. Close collaborations have always been a central ACAM strength, and the 2025 workshop will strive to further strengthen and leverage the regional and international ACAM synergies. Finally, the 2025 ACAM training school will provide an excellent opportunity for early career researchers to directly interact with ACAM lecturers and trainers in a collegial setting to both learn ACAM-related fundamentals and experience practical sessions.
