SSEC SPARC AERI Thermodynamic Profiles at WLEF Tower Site



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.
