Surface and Meteorological Data at Sand Creek, Great Sand Dunes National Park, Colorado, USA in March and April 2019 (NERC Grant NE/R010196/1)
Wind, sediment transport and surface morphological data collected at Sand Creek during a month long field campaign in March and April 2019 to investigate protodune development under bimodal winds. Data is used in the accepted paper ‘Dune initiation in a bimodal wind regime’, Journal of Geophysical Research: Earth Surface, by Delorme, P., Wiggs, G.F.S., Baddock, M.C., Claudin, P., Nield, J.M. and Valdez, A. (accepted 18th September 2020, article reference number 2020JF005757R; https://repository.lboro.ac.uk/articles/Dune_initiation_in_a_bimodal_wind_regime/12973817) Surface morphological data: This is terrestrial laser scanned (TLS) data collected of the creek sand surface during multiple visits. The data is raw point cloud format in text columns of x, y and z coordinate data. It has been orientation in local format (the origin is located at 13UTM 443152, 4184478). *_full_lowres cover the whole creek surface and the banks on either side. * is the date that the data was collected in yymmdd format. All other data is high resolution section of the actual creek surface within the channel. Each data set uses the same coordinate system. Data can be viewed in any spatial software. Wind and sediment data were collected from a fixed point on the eastern edge of the creek channel. The data is in csv file format with column titles and can be viewed in any text or database software. See Delorme et al. (accepted) for more details.

Surface morphological data: Scans were undertaken using a Leica P50 Scanstation TLS (all dates except November when a C10 Leica Scanstation TLS was used). The TLS was placed on a tripod at a height of 1.5 m and with a resolution setting of 0.0016 m at 10 m for an instrument sensitivity of 1,000 m for the P20 and a resolution setting of 0.001 m vertical and 0.005 m horizontal at 10 m for the C10. Scans were aligned using fixed targets with a mean absolute error of registered scans of 0.005 m across the entire measurement period. Wind and sediment data were measured at a height of 3.17 m using a Gill 2D sonic anemometer with co-located measurements of saltation activity from a Sensit mass transport monitor. The anemometer and Sensit were connected to a Campbell CR800 Series datalogger with data recorded at a frequency of 0.1 Hz. See Delorme et al. (accepted) for more details.
