IAS2024 coastal sea level dataset

A new dedicated coastal sea level dataset called International Altimetry Service 2024 (IAS2024) for monitoring sea level changes along the world’s coastlines has been presented. The 'track' folder contains the Monthly sea level anomaly (SLA) time series at 20-Hz along-track points for different ground track segments from Jason missions over global coastal oceans, while the 'virtual' folder contains the SLA time series at three sets of altimeter-based virtual stations along the world's coastlines. These three sets of virtual stations are named as onshore, nearshore and offshore virtual stations, which are derived over 0-10 km, 5-15 km and 10-20 km coastal strips. Note that the above datasets can be used to monitor the coastal sea level changes and to investigate the spatial variation of sea level from offshore towards the coast.
