Abstract: In this paper we introduce briefly the integrated meteorological observation items carried out by Dali National Climate Observatory in recent ten years. Then, we systematically summarize main research results as follows: the special atmospheric observation data assessment and quality control technology, the local circulation over the Diancang Mountain -Erhai Lake area, the characteristics of atmospheric vertical structure and planetary boundary layer height, the matter and energy exchange of landatmosphere system, and the characteristics of typical weather events such as heavy rain, heavy snow and high wind. Furthermore, we summarize the applications of special atmospheric observation data in meteorological forecast, numerical simulation assimilation test and airport aircraft bumps. Finally, we propose some research direction for Dali National Climate Observatory in the future.
