This paper presents an overview of important developments in the atmospheric boundary layer physics from 2012 to 2017 at the State Key Laboratory of Atmospheric Boundary Layer Physics and Atmospheric Chemistry (LAPC), Institute of Atmospheric Physics, Chinese Academy of Sciences. The developments include:improving the accuracy of measurements of UAT-2 ultrasonic anemometer, measurement studies of the atmospheric boundary layer over difference land surfaces (Qinghai-Tibetan Plateau, grasslands, deserts, lakes, sea and etc.), theoretical studies on the atmospheric turbulence and the coherent structure in gusty disturbances, and improvements in the parameterization of atmospheric numerical simulations. Some future research prospects are also presented in this paper.
