Data sets
Chemical composition and snow physical properties of 35 profiles in a snow trench at Dome C, East Antarctica (2019) A. Ooms et al. https://doi.org/10.5281/zenodo.18300845
Short summary
This work presents a new approach to the estimation of accumulation rates at Concordia Station, East-Antarctica, for the last 20 years, from a new data set of chemical tracers and snow micro-scale properties measured in a snow trench. Multi-annual and meter to decameter scale variability of accumulation rates are compared again in-situ measurements of surface laser scanner and stake farm, with very good agreement. This further constrains SMB estimation for Antarctica at high temporal resolution.
