| Abstract: | Based on the radiation and fluxes data observed at Miyun station in Beijing in January,April,August,October 2007,the radiation balance,albedo and energy balance under different types of synoptic conditions including clear and cloudy days on heterogeneous underlying surface are analyzed.The results shows that:(1) The energy balanceclosure(OLS) was 82%,97%,72%and 83% in January,April,August and October,respectively.The total energy balanceclosure was 76%.These indicated that the quality were good;(2) As the c... |
