Glacier mass change has crucial impacts on hydrology, sea level rise, and climate change. Geodetic and glaciological mass balance observations so far have insufficient resolution to capture processes occurring on small spatial and/or short temporal scales. However, a permanent Terrestrial Laser Scanning (TLS) station adjacent to Hintereisferner (HEF, Ötztal Alps, Austria) provides daily Digital Elevation Models (DEMs), which allow closing spatiotemporal gaps in established glacier monitoring methods. An uncertainty assessment showed that smaller-scale processes, such as snow deposition and redistribution with a vertical spatial scale >0.10 m can be investigated with the TLS setup at HEF
