Aeolian Saltation Data at Duck, NC - 4 August 2020

Datasets of sequence linescan lidar, Sensit aeolian sediment transport data, and wind measurements were collected at the US Army Engineer Research and Development Center's Field Research Facility on 4 August 2020 associated with the passage of the Tropical Storm Isaias. 

Dataset 1. Matlab .mat files are provided with 30 minutes of linescan lidar data, with the following variables;

Xmat = cross-shore distance of each point in meters in the US Army Corps of Engineers Field Research Facility local coordinate system

Ymat = alongshore distance of each point in meters in the US Army Corps of Engineers Field Research Facility local coordinate system

Zmat = vertical elevation of each point in meters in the NAVD88 datum

Amat = amplitude of returned lidar signal

Tmat = time of each point sample in matlab format

reflectance = reflectance of the returned lidar signal

Each lidar linescan measures at approximately 7.1 Hz for 30 continuous minutes. The filenames include the date in yyyymmdd-HHMM-SS format for the start time of the scan. 

Dataset 2: Processed saltation height data generated from the point clouds are provided as a grid in 'IsaiasLidarSaltationHeight_202008040900to202008041500.mat' . The variables in the file are 'saltation_times' which are 1s time intervals in matlab format, 'saltation_distances' which are 0.1 m grid cells in the FRF cross-shore coordinate system, and 'SALTATION_HEIGHT_m'  providing the lidar-derived maximum saltation height for each grid cell and time interval with available data between 4 August 2020 0900 UTC to 4 August 2020 1500 UTC.

Dataset 3: An excel spreadsheet entitled "InSituData.xlsx' provides time series data of 1Hz wind speed  using a Dyacon WSD-1 cup anemometer collected from a 5 m mast on the beach and logged using a Dyacon MDL-700 data logger. 1 Hz data of sediment counts from a stacked array of Sensit H14-LIN horizontal flux sensors, which were logged using a Campbell CR1000X logger, and were located at 8 cm, 12 cm, and 16 cm off of the bed in close proximity to the lidar are also provided.
