The Asian Tropopause Aerosol Layer (ATAL) is a thin layer of aerosol with a thickness of about 3-4 km, which appears regularly at the height of the tropopause layer during the Asian summer monsoon (ASM) period over the Tibetan Plateau. How is it formed? Where are aerosols from? There questions have been debated since the discovery of ATAL in 2011.
