基于WACCM+DART的临近空间大气环境同化分析产品数据集（2016.02.05-2016.02.15）

基于WACCM（Whole Atmosphere Community Climate Model）中高层大气模式和DART（Data Assimilation Research Test-Bed）资料同化系统，利用SABER（Sounding of the Atmosphere using Broadband Emission Radiometry）和MLS（Microwave Limb Sounder）的臭氧观测产品，作者开展临近空间大气资料同化试验，研发了基于WACCM DART的临近空间大气环境同化分析产品数据集。该数据集包含2016.02.05-2016.02.15期间全球从近地面至热层底部每日逐6小时的气压（PS）、气温（T）、经向风（VS）、纬向风（US）、臭氧浓度（O₃）等大气参量的集合平均同化分析场。数据集由1个文件组成，存储格式为.nc，数据量为1.11 GB （压缩为1个文件，数据量633 MB）。与该数据集相关的部分研究成果已发表在《大气科学》2019年第43卷第2期。

Using ozone observation products from the Sounding of the Atmosphere using Broadband Emission Radiometry (SABER) and Microwave Limb Sounder (MLS), the authors conducted near-space atmospheric data assimilation experiments based on the Whole Atmosphere Community Climate Model (WACCM) middle and upper atmosphere model and the Data Assimilation Research Test-Bed (DART) data assimilation system, and developed a near-space atmospheric environment assimilated analysis product dataset built upon the WACCM-DART framework. This dataset contains ensemble mean assimilated analysis fields of multiple atmospheric parameters including surface pressure (PS), air temperature (T), meridional wind (VS), zonal wind (US), and ozone concentration (O₃) across the global domain, from near-surface to the bottom of the thermosphere, at 6-hourly intervals during the period from February 5, 2016 to February 15, 2016. The dataset consists of a single file with the .nc storage format, with an uncompressed data size of 1.11 GB, and the compressed single file has a size of 633 MB. Portions of the research findings related to this dataset have been published in *Chinese Journal of Atmospheric Sciences*, Vol. 43, No. 2, 2019.
