I graduated from the Research Center for Eco-Environmental Science, Chinese Academy of Sciences, in 2006 with a doctoral degree. After working at the Institute of Urban Meteorology, I focus on urban flux observation, analysis, and simulation. Based on eddy fluxes observations in Beijing city, fluxes values, temporal variation characteristics, and energy budget among sites will be compared and analysed; differences in flux observation results between Beijing and foreign cities will be discussed and analysed, moreover, the relationship between the parameters of land cover type and percentage, as well as building height and layout and ratios of sensible and latent heat fluxes to the net radiation will be studied. I am currently working on optimising the parameterisation scheme of SUEWS to improve the simulation effect of radiation and energy fluxes.
