A Study of Suburban Energy Balance of Beijing City in Summertime

The suburban energy partitioning was examined by using the data collected in Beijing city during the period from July to August in 2007. The results show that daily mean values of net radiation, latent heat flux and sensible heat flux for all the measurement days was 111.3 W/m², 65.7 W/m² and 22.9 W/m², respectively. Meanwhile, daily mean values of net radiation, latent heat flux and sensible heat flux for clear days was 161.1 W/m², 80.6 W/m² and 36.7 W/m² respectively. Energy partitioning was dominated by latent heat flux under both clear and all sky conditions, the mean diurnal Bowen ratio values was 0.67 and 0.54.
