Almost half of the world's population rely on the Asian summer monsoon (ASM) precipitation for agriculture, energy, industry, and local water resources. Small changes in the onset, intensity, and duration of the ASM can result in considerable socio-economic impacts. An observed drying trend in ASM precipitation in the latter half of the 20th century opposed the anticipated impact of increasing greenhouse gas emissions, and has largely been attributed to increases in anthropogenic aerosol.
