Abstract: The simulation of urban surface energy balance process is one of the key processes of urban atmospheric boundary layer numerical model, nevertheless, there’s less work for applicability and simulation performance towards different parameterization at present. We compare the simulation results of different urban parameterization schemes consisting of The Single Layer Urban Canopy Model (SLUCM), The Local-scale Urban Meteorological Parameterization Scheme (LUMPS), The Surface Urban Energy and Water Balance Scheme (SUEWS) and The Community Land Model Urban (CLMU) model with the observed data to analyze their simulated performance for surface energy balance in Nanjing. The results illustrate that: 1)All models have a good performance for the simulation of the net radiation, the root mean square error is generally lower than 50% of the sensible heat, and the simulations of latent heat and heat storage are poorer . 2) The models underestimates the value of net radiation, among which SLUCM model simulates optimally, the annual deviation is about 7.7%, and the root mean square error is about 10-20Wm-2. The simulation of SUEWS model is better than other models for sensible heat flux. Its daytime deviation is less than 7%. As for latent heat flux, the performance of CLMU model is excellent, especially in summer, autumn and winter, the average deviation is about 12.5%. the simulation of SLUCM is 10 percent deviating from the observation of the heat storage, which implies its better representation, And it also can be find from the issue that the root mean square error is generally lower than 50% of other models. 3) In general, the simulation in winter and autumn is better than other seasons, and the nighttime characteristics of observed heat flux are more optimal reproduced comparing with daytime performance by models. The results of this paper provide a reference for the selection and improvement of urban canopy model in numerical simulation.
