Although Monsoon Asia is one of the current “frontiers” for atmospheric chemistry, the region is not well connected to the international science community. Corresponding to emerging environmental issues including severe air pollution, the atmospheric chemistry community in Monsoon Asia is rapidly growing at both national and international levels, and policymakers need scientific evidence and support. However, there is large asymmetry between countries. Therefore, coordination across nations is needed to build an atmospheric science community in Asia, especially with a focus on countries that are not big enough to have national working groups.
