Highlights GNSS-Reflectometry accuracy was evaluated in the Antarctic coastal area. GPS and GLONASS L1 Signal SNR were analyzed based on LSP method. The contribution of the multi GNSS concept to sea level monitoring was found as 8 %. Correlation with tide gauge and GNSS-R resultswas found as 0.91. Sea level change based on GNSS-R RMSE was found as 14.1 cm.
Abstract Antarctica is a continent that crucial for studying climate change and its progression across time, as well as analyzing and forecasting local and global change. In this environment, due to the challenges caused by sea-level rise, storm surges, and tsunamis, sustainability is a critical concern, particularly for coastal regions. As a result, the long-term observations that will be conducted in Antarctica are critical for monitoring the adverse impacts of climate change. In recent years, many monitoring approaches, both space, and ground-based are performed to monitor sea/ice level trends in space-based scientific investigations conducted in and around the region. In the study, based on one year of observations from the Palmer GNSS Station, the GNSS Reflectometry technique was used to measure the sea level on the Antarctic Peninsula (PALM). GNSS Station observations were analyzed with a Lomb-Scargle periodogram to monitor sea-level changes, and results were validated with data from a co-located tide gauge (TG). The results show that the correlation between GNSS-R sea-level changes and tidal sea-level changes is found as 0.91.
