基于OMI数据的东三省AOD的分布特征及其影响因素分析VIP专享

1基于 OMI 数据的东三省 AOD 的分布特征及其影响因素分析摘要：利用 AOD 检测仪（OMI）卫星反演的 AOD 厚度产品，讨论了 2007—2018 年间东北三省区域对流层 AOD 厚度的时空分布变化特征及其相关的影响因子，结果表明：近 12 年来对流层 AOD 的厚度整体呈现周期性变动趋势，平均厚度为 2.306，最大厚度达到了 3.234，且高值区域逐渐扩大。空间分布上，高值区域主要分布在每年的五月份附近区域，低值区域主要分布在每年的一月份附近区域， AOD厚度年变化波动较大，呈现周期性趋势。12 年中，每年的一月份出现最小值，五月份出现最大值，而2009 年的 12 月份的 AOD 厚度最小，2015 年的 6 月份 AOD 的厚度最大。东三省区域对流层 AOD 季水平：夏季>春季>秋季>冬季。年均降雨量会降低大气中固体颗粒物的含量致使 AOD 削减，年均气温的变化对 AOD 的影响不大。然而，12 年来区域第二生产力、汽车保有量、空气相对湿度、平均日照时数是影响 AOD 厚度的主导因素。关键词 : 对流层 AOD; OMI；时空分布；影响因素；东三省Distribution characteristics and influencing factors of analysis based on OMI data of AOD of the three Provinces of Northeast China Abstract : The use of AOD detector (OMI) satellite inversion of the thickness of AOD products, discusses the three northeastern provinces between 2007 and 2018 regional tropospheric AOD of thickness the changes of time and space distribution and the influence factors, the results show that the AOD troposphere nearly 12 years present the cyclical change trend, the thickness of the average thickness is 2.306, the biggest thickness is 3.234, and the high value area is increasing spatial distribution, the high-value area are mainly distributed in the neighborhood of each year in May, the low-value region is mainly distributed in the region around January each year. The AOD thickness fluctuates greatly on an annual basis and presents a cyclical trend with minimal thickness of AOD in December 2009, 2015 in June. Quarte...
