针对SHS探测仪的中高层OH自由基临边观测仿真研究
|
摘要
大气OH自由基是大气中各组分光化学反应的重要媒介,对大气其他成分的形成和转化起重要作用。利用MLS传感器2005年—2009年的OH全球浓度数据产品构建OH浓度时空数据库和Lifbase光谱分析软件构建OH发射光谱数据库,改进了SCIATRAN辐射传输模型,计算了基于空间外差光谱(SHS)技术的探测仪的临边探测仿真图像,并提取了大气OH自由基荧光发射在观测能量中的贡献。基于辐射传输理论,通过定量计算分析了仿真过程中各个参量不确定度对仿真结果和OH荧光能量的定量影响。该研究结果不仅能为我国构建中高层OH自由基探测仪提供科学理论支撑,还能为探测仪器相关参数设计提供依据。
OH radicals in atmosphere,an important mediator of the photochemical reactions between various atmospheric compositions,play a key role in the formation and transformation of other atmospheric components.Based on the OH concentration spatiotemporal database constructed by MLS global observation results of OH, and the OH emission spectra database from Lifbase,SCIATRAN was modified according to the radiation transmission theory.The simulated image of spatial heterodyne spectrum(SHS)detector was obtained in the state of limb scanning and the contribution of atmospheric OH radical fluorescence emission in observing energy was extracted.Based on the radiation transmission theory,the quantitative influence of the uncertainty of each parameter in the simulation process was analyzed quantitatively.The results can not only provide scientific theoretical supports for the construction of detector for mesospheric OH radical,but also provide the basis for the design of relevant parameters of detector.
