SPARC contains a variety of instruments capable of in situ or remote observations of the earth's surface and the troposphere. The remote instruments include the Atmospheric Emitted Radiance Interferometer (AERI), capable of retrieving thermodynamic profiles of the boundary; the High Spectral Resolution lidar, which measures backscatter and depolarization while accounting for aerosol and molecular scattering in its measurements; and a Doppler lidar wind profiler capable of measuring both horizontal and vertical winds. In addition, in situ observations of the atmosphere are obtained from a surface meteorology station and a radiosonde system.
To date, SPARC has participated in two large-scale field campaigns: the Front Range Air Pollution and Photochemistry Experiment (FRAPPÉ) and the Plains Elevated Convection at Night (PECAN) project. Highlights from the unique dataset generated by the combined instrumentation of SPARC will be presented and future collaborative opportunities will be discussed.
