​The South Asian Pollution Experiment (SAPOEX-2016), an international measurement campaign led by Prof. Örjan Gustafsson (an ABC Scientist), will be held in January-February 2016 at Maldives Climate Observatory-Hanimaadhoo (MCOH) and some selected measurement sites in India and Bangladesh. The scientific objectives of SAPOEX-2016 are characterization of aerosol properties for South Asian region; investigation of processing of different aerosol components during long-range transport; and monitoring of background conditions which influences long-range transport and processing of the aerosols. The research output of SAPOEX-2016 will improve our understanding on regional scale emissions and their impacts on regional climate system and human health. This is an international measurement campaign involving scientists from Stockholm University, Sweden; Finnish Meteorology Institute, Finland; Indian Institute of Science, Bangalore, India; Indian Institute of Technology, Kanpur, India; Dhaka University, Bangladesh; Maldives Meteorology Service, Maldives; and Maldives National University, Maldives.
