Meteorological and multi-scale topographic data from survey pole, UAV, TLS and ALS used to analyse glacier aerodynamic roughness on Hintereisferner glacier, Austria, August 2018 - VERSION 2.0

Meteorological variables (wind speed, air temperature and wind direction) were collected using two wind towers. Photogrammetric data were collected using a pole-mounted digital camera and DJI Phantom 3 UAV. LiDAR data collected via terrestrial and airborne laser scanning. Fieldwork carried out at Hintereisferner glacier, in the Oetztal Alps region, Tyrol, Austria, from 1-15 August 2018 by Joshua Chambers, Thomas Smith and Mark Smith. Terrestrial laser scan (TLS) data collected by Rudolf Sailer. Airborne laser scan (ALS) data originally from Open Data Austria, see Sailer et al. (2012). One wind tower recorded for the entire study duration, the second was moved to different plots every ~4 days. Photogrammetric data were collected on 8, 10, 11, 12 and 13 August. TLS scans were split into upper- and lower-glacier, and completed on 3, 7, 12 and 16 August. Data were used to examine the relations between glacier aerodynamic roughness and sampling resolution, and to develop a correction factor for roughness derived from coarser resolution data.

Fieldwork was funded by an INTERACT Transnational Access grant awarded to Mark Smith under the European Union H2020 Grant Agreement No. 730938. Joshua Chambers is supported by a NERC PhD studentship (NE/L002574/1). Ivana Stiperski was funded by Austrian Science Fund (FWF) grant T781-N32.

Explanation: See the referenced specification

Pass: No

Statement: Wind speed is ±0.05 m s-1

Wind direction is ±1 %

Temperature is ±0.1 °C

GPS accuracy <1 cm

Photogrammetric 3D root mean square (RMS) error was ±0.03 m and RMS re-projection error was 1.66 pixels (2.6 µm)

NoData values used either NaN in Matlab or -32767 as is convention in ArcMap.

Changes since version 1.0:

PlotData:

z0DEM calculated for each plot and extracted at wind tower location, rather than taken as a mean of whole plot as in version 1.0. Correction factors and corrected glacier aerodynamic roughness calculated using the new model outlined in Chambers et al. (in prep).

TLSData:

Both files replaced after processing with new correction factors.

ALSData:

Corrected glacier aerodynamic roughness DEM replaced after processing with new correction factors.
