The Indo-Gangetic Plain (IGP; northern Pakistan, N. India and Bangladesh) as well as the eastern corridor of China are two examples of hotspot regions with massive anthropogenic effects on public health and climate with a myriad of cascading effects on other environmental systems.
Research in this field takes a long-term perspective, spanning several decades, to identify changes in the sources, composition, and climate effects of both gases and aerosols. This includes close collaboration with international partners to enable advanced, strategically located atmospheric observatories that are well equipped and collect samples for a wide range of analyses at Stockholm University, including powerful isotope studies of both emission sources and atmospheric processes.
