SSEC SPARC AERI Thermodynamic Profiles at WLEF Tower Site. Version 1.0

This dataset contains the thermodyncamic, vertical profiles of temperature and water vapor from the SSEC Portable Atmospheric Research Center (SPARC) Atmospheric Emitted Radiance Interferometer (AERI) collected at the WLEF site for the CHEESEHEAD project. The SSEC Portable Atmospheric Research Center (SPARC) was deployed at the WLEF-TV tall tower site (45.94554, -90.27312) for the duration of CHEESEHEAD. Among the instruments deployed aboard SPARC is the Atmospheric Emitted Radiance Interferometer (AERI), from which high temporal resolution atmospheric profiles can be retrieved through a physical retrieval. Data have been processed into temperature and water vapor mixing ratio profiles with a temporal resolution of 5 minutes and are output onto a vertical grid with spacing that decreases approximately exponentially with height. The data cover the period from 2 July through 11 September 2019. On 12 September 2019, the SPARC AERI suffered a catastrophic failure possibly associated with an uncompensated power surge. No retrievals are available from that date onward through the conclusion of the experiment. Please see the readme file for more information.

本数据集包含SSEC便携式大气研究中心（SSEC Portable Atmospheric Research Center, SPARC）的大气发射辐射干涉仪（Atmospheric Emitted Radiance Interferometer, AERI）所采集的热力学特性数据，以及温度、水汽垂直廓线，相关数据为CHEESEHEAD项目在WLEF观测站点获取。CHEESEHEAD项目实施期间，SSEC便携式大气研究中心（SPARC）被部署在WLEF-TV高塔观测站点（坐标45.94554, -90.27312）。SPARC搭载的仪器包含大气发射辐射干涉仪（AERI），通过物理反演方法可从该仪器获取高时间分辨率的大气廓线。数据已处理为时间分辨率5分钟的温度与水汽混合比廓线，并输出至垂直网格中，该网格的间距随高度近似呈指数递减。数据覆盖时段为2019年7月2日至2019年9月11日。2019年9月12日，SPARC搭载的AERI发生灾难性故障，疑似与未补偿的电涌有关。自此至实验结束，无可用的反演数据。更多详情请参阅自述文件（readme file）。
