AB: The DOE Cloud and Atmosphere Land Surface Interaction Campaign or CLASIC experiment was designed to further better understanding of the effects of the land surface on cumulus convection. The intensive observation period (IOP) of this project was conducted in the summer of 2007 and was distributed throughout much of the ARM-Climate Research Facility, Southern Great Plains region in Oklahoma. The experiment utilized a range of measurement platforms. From satellites and high-altitude aircraft, to surface measurements. At the surface level, ten eddy covariance flux towers were distributed at three geographically separated sites. These towers measured fluxes of carbon, water, and energy, as well as components of the radiation budget. The data set generated by these towers will not only be used in local process-based investigations, but will also be used as calibration points for some of the aircraft measurements, and will server as the basis of regional up- scaling efforts. To insure consistency of synthesis products derived from this flux tower data set, an instrument intercomparison was undertaken prior to field deployment. We report here, the results of this comparison for 14 different parameters among the participating flux tower groups.
