摘要
根据常州市环境监测中心2013-2015年黑碳气溶胶小时平均浓度资料,分析了常州市黑碳浓度的变化特征以及气象条件对黑碳浓度的影响。结果表明,2013-2015年期间,非降水日和降水日黑碳气溶胶日变化为双峰型结构,峰值出现在当地时7-9时和19-22时,谷值出现在12-16时。降水日受雨水冲刷作用,黑碳气溶胶日变化幅度减小。从年变化看,黑碳气溶胶年平均浓度呈逐年下降的趋势,2013年1月和12月黑碳浓度异常高于其他月份,2014年6-9月黑碳浓度也相对较高,2015年环境空气质量整体改善,黑碳浓度较低。气象条件对黑碳浓度影响显著,非降水日,黑碳浓度与温度和相对湿度呈倒U型关系,降水日黑碳浓度整体上随相对湿度的增加而增加。黑碳浓度随着风速增加而减小,当常州市区主导风向为偏西风时浓度最高。
