Data Quality Flags for ACE-FTS Level 2 Version 5.2 Data Set

Data quality flags generated for the Atmospheric Chemistry Experiment Fourier Transform Spectrometer (ACE-FTS) Level 2 (L2) version 5.2 data products. These data quality flags are generated using the technique described in Sheese et al. (2015). One netCDF file is produced for each species, isotopologue or parameter retrieved from the ACE-FTS spectra for version 5.2. Each file contains the data quality flags organized by occultation (orbit number and occultation type). Note, the ACE-FTS Level 2 version 5.2 profiles are not included in these files. The data quality flag files are updated monthly as new Level 2 version 5.2 data are produced for ACE-FTS.本数据集为大气化学实验傅里叶变换光谱仪（Atmospheric Chemistry Experiment Fourier Transform Spectrometer，ACE-FTS）5.2版二级（Level 2, L2）数据产品配套生成的数据质量标记。此类数据质量标记基于Sheese等人2015年发表的方法生成。针对5.2版数据中由ACE-FTS光谱反演得到的各物种、同位素异构体或参数，均对应生成一个netCDF格式文件。每个文件内的数据质量标记均按掩星（含轨道编号与掩星类型）分类编排。请注意，本批文件未包含ACE-FTS 5.2版二级数据廓线。随着ACE-FTS新的5.2版二级数据产出，此类数据质量标记文件将按月更新。
