VOCs in the Troposphere Retrieved from ACE Satellite Measurements

有机分子和氮氧化物的排放是造成空气污染的原因。空气质量可能是大气科学中最重要的问题，因为它对人类健康和生态系统有负面影响。微量有机分子导致对流层臭氧的产生，这是人为气候变化的一个主要因素。我们建议利用大气化学实验（ACE）卫星的测量数据在区域和全球尺度上研究自由对流层中的有机分子。我们计划从ACE上的红外傅立叶变换光谱仪的观测中检索丙酮和丙烷的剖面。丙烷的必要光谱数据将从实验室测量中获得，这些测量主要是在卢瑟福阿普尔顿实验室的nerc支持的分子光谱设施中进行的。操作ACE检索代码的研究版本将用于获取大气剖面。ACE的全球测量数据集将与几种化学传输模型进行比较，目的是改进模型预测。这些化学模型在预测气候变化方面很有用。

The emission of organic molecules along with nitrogen oxides is responsible for air pollution. Air quality is perhaps the most important issue in atmospheric science because of its negative effect on human health and ecosystems. Trace organic molecules lead to the production of tropospheric ozone, which is a major factor in anthropogenic climate change. We propose to use measurements from the Atmospheric Chemistry Experiment (ACE) satellite to study organic molecules in the free troposphere on a regional and global scale. We plan to retrieve the profiles of acetone and propane from observations made with the infrared Fourier transform spectrometer on-board ACE. The necessary spectroscopic data for propane will be obtained from laboratory measurements made primarily at the NERC-supported Molecular Spectroscopy Facility at Rutherford Appleton Laboratory. A research version of the operational ACE retrieval code will be used to obtain atmospheric profiles. The set of global measurements from ACE will be compared with several of chemical transport models, with the goal of improving model predictions. These chemical models are useful in predicting climate change.
