華北平原忻州郊區(qū)站點夏季輻射和氣溶膠特性研究(英文)
發(fā)布時間:2021-12-29 07:21
基于2014年夏季地基觀測數(shù)據(jù)分析了華北平原忻州郊區(qū)站點輻射和氣溶膠特性。結(jié)果表明,晴空和云天條件下的長波輻射最大值和最小值分別出現(xiàn)在地方時17:00 (392.6 W m-2)和06:00 (360.0W m-2);總輻射,直接輻射,散射輻射,光合有效輻射,紫外A和紫外B輻射最大值出現(xiàn)在~13:00。氣溶膠粒徑呈雙峰結(jié)構(gòu),粗細模態(tài)峰值分別為~5微米和0.1-0.2微米。氣溶膠光學厚度大于0.4 (400nm)時主要為黑碳覆蓋粗粒子類型氣溶膠(85.7%),使得氣溶膠單次散射反照率(0.81)低于華北平原其他測站典型值(-0.90);消光和吸收埃斯特朗指數(shù)平均值分別為1.14±0.15和0.58±0.28;地表氣溶膠直接輻射強迫瞬時平均值為-138.9±33.0 w m-2。
