Atmospheric data was collected at the University of Wisconsin - Madison using two high spectral resolution instruments: an active remote sensor in the visible, the High Spectral Resolution Lidar (HSRL); and a passive sensor in the infrared, the Atmospheric Emitted Radiance Interferometer (AERI). These instruments simultaneously measure a vertical atmospheric column that is advected into the instrument's field of view. A description of their data acquisition techniques and capabilities will be described in the following subsections. The Cross-chain Loran Atmospheric Sounding System (CLASS) was utilized to track locally-launched radiosondes, which provide atmospheric state information required to invert the AERI and HSRL data.

Radiosondes were released from the Atmospheric and Oceanic Sciences (AOS) rooftop, where the AERI and CLASS reside during local data acquisition. The HSRL is located adjacent to the AOS building in the loading dock. Approximately 40 m separates the HSRL from the AERI.
