遥感 太赫兹临边探测仪 中高层 OH自由基 时空分布 remote sensing microwave limb sounder high-level OH radicals spatio-temporal distribution
摘要
基于太赫兹临边探测仪(microwave limb sounder, MLS)传感器2005~2009年OH自由基、臭氧、水汽观测数据,分纬度、季度分析了平流层和中间层OH自由基时空分布特征及其与臭氧、 水汽的关联性。结果表明:不同纬度中高层OH自由基浓度变化分异明显,存在年周期性;全球中高层OH自由基浓度季度变化显著; 平流层上部OH自由基主要受太阳辐射和臭氧浓度变化影响;中间层OH自由基与水汽浓度变化关系密切。
Abstract
Based on the OH radicals, ozone, water vapor observation data of microwave limb sounder(MLS) sensor from 2005 to 2009, the spatio-temporal distribution of OH radical and its association with ozone and water vapor in the stratosphere and mesosphere were analyzed. The results indicate that the OH radical concentration has obvious disparity in different latitude area, and there are obvious yearly periodic variations. OH radical concentration of global high-level quarter changes significantly. In the upper stratosphere, OH radical concentration is mainly influenced by changes of solar radiation and ozone concentration. In the mesosphere, OH radical concentration is closely related to the water vapor concentration variation.
