摘要
气溶胶光学特性对气溶胶直接辐射强迫有重要的影响。采集了北京、香河、兴隆、敦煌四个不同地区的气溶胶光学特性地基观测数据,利用SBDART辐射传输模式模拟计算获取了四个地区的气溶胶直接辐射强迫,通过对比分析这四个地区的气溶胶辐射强迫得到了气溶胶辐射强迫效率同气溶胶光学特性的相关性。该研究结果对分析气候模式和评估环境能源结构具有重要的参考意义。
Aerosol optical properties are the key factors for direct radiative forcing. The aerosol optical properties and their variations were observed in four different regions of Beijing, Xianghe, Xinglong, and Dunhuang. The four different regions aerosol direct radiative forcing were calculated from the SBDART model based on the observed aerosol data. The results of quantitative relationship between the aerosol optical properties and aerosol radiative forcing efficiency were obtained with the comparative analysis of the four regions of aerosol radiative forcing. The results have important reference significance in analyzing climate models and evaluating environmental energy structure.
