GNSS refractometry data from Davos Laret, Switzerland in 2021/22

This data is collected for the feasibility study on (near) real-time snow water equivalent (SWE) retrieval using the GNSS refractometry method, described in Steiner et al., submitted to Sensors, 2022. 

GNSS baseline solutions, stored in zipped binary python pickle format (ENU.pkl) are available from real-time kinematic (RTK) GNSS processing for the season 2021/22  for the Swiss Alpine test sites Davos Laret, operated by the WSL Institute for Snow and Avalanche Research SLF (WSL SLF), Switzerland. Additionally, the raw GNSS Rinex data (1s sampling interval, multi-system, multi-frequency) are available for the base and rover receiver from the same setup. SWE reference data from a snow scale and manual observations were provided by the WSL SLF. The data processing and the SWE estimation results are revealed in Steiner et al. 2020 and 2022.
