This dataset contains Vertical Land Motions have been estimated as the difference between the altimeter coastal sea level (SL_cci+ v1.1 dataset) and tide gauges measurements (from the PSMSL network). Spatial interpolation has allowed the production of a regularly spaced coastline profile of vertical land movements together with their uncertainties.

Altimeter input data measurements are from the Jason-1, Jason -2 and Jason-3 satellite missions during the period January 2002 - January 2020, which have been processed to produce high resolution (20 Hz, corresponding to an along-track distance of ~300m) sea level anomalies, in order to provide long-term homogeneous sea level time series as close to the coast as possible.

The product benefits from the spatial resolution provided by high-rate data, the Adaptive Leading Edge Subwaveform Retracker (ALES) and the post-processing strategy of the along-track (X-TRACK) algorithm, both developed for the processing of coastal altimetry data, as well as the best possible set of geophysical corrections.

The product has been developed within the sea level project of the extension phase of the European Space Agency (ESA) Climate Change Initiative (SL_cci+).
