Abstract

Estimates of seasonally dependent multiyear trends in the mass concentration of near-surface aerosol are presented based on measurements at the Zvenigorod Research Station of the A.M. Obukhov Institute of Atmospheric Physics, Russian Academy of Sciences, in 1991–2018. The analysis was performed by the method of multiple linear regression taking into account data autocorrelation on long timescales. Statistically significant negative trends were derived for the spring and summer periods of 1991–2002 and 2013–2018, respectively; possible causes for the trends are discussed.

俄罗斯科学院AM Obukhov大气物理研究所Zvenigorod研究站近表面气溶胶质量浓度的多年趋势

摘要

基于1991-2018年在俄罗斯科学院AM Obukhov大气物理研究所的Zvenigorod研究站进行的测量,得出了近地表气溶胶质量浓度随季节变化的多年趋势的估算值。考虑到长时间范围内的数据自相关性,使用多元线性回归方法进行了分析。在1991-2002年春季和夏季和2013-2018年春季分别得出了具有统计意义的负趋势;讨论了趋势的可能原因。
