Short summary

An enhanced aerosol layer in the upper troposphere--lower stratosphere was observed by a COBALD over the Tibetan Plateau, in the summer of 2014. The color index of the enhanced aerosol layer indicates the prevalence of dominant fine particles with a mode radius < 0.1 μm. Unlike the very small particles at low relative humidity (RHi < 40%), the relatively large particles in the aerosol layer were generally very hydrophilic as their size increased dramatically with relative humidity.
