Research interests/activities
1) Stratosphere-Troposphere Exchange (STE) processes in the Tropical Tropopause Layer (TTL)
Tracer distribution in the upper troposphere/ lower stratosphere
Physical, chemical and radiative processes in the TTL
Water vapor distribution and dehydration process in the TTL
2) Physical and chemical processes in the marine boundary layer (MBL)
