| Summary: | <!--!introduction!--> Time series of sea level data in the polar regions are a challenging task due to the presence of sea ice and severe weather conditions during most of the year. Long-term sea level measurements are crucial for sea level trend analysis under a climate change scenario, and for establishing the reference level for many applications. These records are obtained using in-situ tide gauges and, since the 1990s, satellite altimetry. The main aim of this work is the validation of Copernicus Sentinel-3B SAR altimetry data using a ground-truth station (pressure sensor) located in Livingston Island (South Shetland archipelago, about 100 km away from the Antarctic Peninsula). Time series of sea level span 4 years: from November 2018 to December 2022. Altimetry data are from the repository available in the European Space Agency Earth Console Parallel Processing Service (P-PRO). They are obtained in the crossover of two tracks (ascending orbit #0374 and descending #0109) near the tide gauge ... : The 28th IUGG General Assembly (IUGG2023) (Berlin 2023) ... |
