GNSS Dataset for ALTG and SHRN Coastal Stations

This dataset contains GNSS observation files from the ALTG (Liverpool, UK) and SHRN (Sheerness, UK) coastal stations, provided by the National Oceanography Centre (NOC). The data were used in the study “Improving GNSS-IR sea level retrievals using WinLSP with damping-aware height-rate correction and normalized IRLS”. The archive consists of: GNSS_Dataset_ALTG_SHRN.zip (main archive) GNSS_Dataset_ALTG_SHRN/ (root folder) ALTG00GBR.zip → daily RINEX compact/CRINEX files for ALTG station (e.g., ALTG00GBR_R_20250010000_01D_05S_MO.crx.gz). SHRN00GBR.zip → daily RINEX compact/CRINEX files for SHRN station. All files are provided in compressed and gzipped format (.crx.gz) with a 1-day duration and 5-second sampling interval. These data are suitable for GNSS Interferometric Reflectometry (GNSS-IR) sea level analysis and support reproducibility of results presented in the related manuscript.
