Twilight Zone (TZ) is the transition zone surrounding shallow cumulus clouds, which are not always visible to human eyes and can sometimes only be observed by instruments.
A team of scientists from the Key Laboratory of Middle Atmosphere and Global Environment Observation of the CAS Institute of Atmospheric Physics, led by Prof. CHEN Hongbin and Prof. XIA Xiang'ao, finished their two-week intensive observation campaign in the Inner Mongolia grassland in August and brought home rich data of aerosols and clouds. These data are instrumental to understand atmospheric parameters and aerosol variation within the Twilight Zone and their relationships to ambient atmosphere and cumulus.
