Global Attributes:	title: lidarWaveRunup cdm_data_type: Station featureType: timeSeries summary: Lidar Wave Runup data from a time series of wave runup elevations at 945 meters in FRF alongshore collected using a Riegl VZ-1000 or VZ-2000 terrestrial laser scanner mounted on the North lidar tower at the United States Armp Corps of Engineers' Coastal And Hydraulics Laboratory's Field Research Facility (USACE/CHL/FRF) in Duck, NC. The Riegl VZ-1000 is the primary data collection instrument, with the VZ-2000 deployed while the VZ-1000 is being serviced. comment: Lidar point density and accuracy decreases with range. Please check coregQCFlag for a measure of rectification accuracy. history: Measured, rectified, coregistered, and processed at USACE/CHL/FRF. source: VZ-1000 or VZ-2000 terrestrial laser scanner observations from the North lidar tower at USACE/CHL/FRF. sourceUrl: (local files) standard_name_vocabulary: CFv25 Metadata_Conventions: Unidata Dataset Discovery v1.0, CF-1.6 Conventions: CF-1.6 creator_name: USACE/CHL/FRF creator_url: http://www.frf.usace.army.mil/ creator_email: frfwebmaster@usace.army.mil license: These data may be redistributed and used without restriction.
