The Space Science and Engineering Center (SSEC
) Portable Atmospheric Research Center, also known as the SPARC, is a specially designed vehicle outfitted with instruments that make ground-based measurements used for studying the atmosphere.
Based at the University of Wisconsin-Madison, the SPARC has an extensive suite of instruments, including an Atmospheric Emitted Radiance Interferometer (AERI), a High Spectral Resolution Lidar (HSRL), a Surface Meteorology (SurfaceMet) station, a WindPro lidar system, and a radiosonde receiving station.
The SPARC is an upgraded version of the AERIbago
, SSEC's previous mobile lab, which was retired after 20 years of service.
