Timeseries of surface elevation maps at Dome C measured by time lapse laserscanning
The surface was scanned at Dome C almost daily for nearly 3 years using the Rugged Laserscan (RLS) developped by L. Arnaud and G. Picard (IGE). The dataset contains maps of surface elevation (DEM) with a resolution of 5 cm over an area of about 150m2. Maps are available at best daily, when enough valid data were acquired. The RLS and the data are described in G. Picard, L. Arnaud, R. Caneil, E. Lefebvre, M. Lamare, Observation of the process of snow accumulation on the Antarctic Plateau by time lapse laserscanning, The Cryosphere, doi:10.5194/tc-2019-4

The two NetCDF files all the elevation maps with valid data acquired during the 2 periods of acquisition. The difference between these periods is due to the height of installation of the instrument which drives the resolution and extent of the scanned area. The details are provided in the associated publication:
