AB: The NCAR Raman-shifted Eye-safe Aerosol Lidar (REAL) and the Integrated Surface Flux Facility (ISFF) operated from 15 March to 11 June, 2007, for the Canopy Horizontal Array Turbulence Study (CHATS). Lidar aerosol backscatter data at 1.5 microns wavelength were recorded at 1.5 meter intervals to ranges of 5.8 kilometers. Scanning resulted in almost half a million vertical cross-sections and near horizontal slices. The horizontal scans ranged in altitude from meters to tens of meters above the surface and covered approximately 10-square kilometer areas. Scans were repeated at approximately 15 second intervals in order to create time-lapse animations of the flow. The ISFF 30-meter tall tower was located 1.6 km from the REAL. The tower intersected all of the horizontal scans and the vertical scan planes were approximately 10 meters or less from the tower. Time- series of in situ measurements and fluxes from the tower will be compared with the lidar backscatter at that range. Ultimately, by combining the spatial imaging and time-lapse visualization capability of the lidar with the precision of the in situ measurements, we hope to improve understanding of near-surface fluxes and their impact on the larger scales.
