  abstract = {{O}bserving sea level and its variations is of great importance for many scientific, societal and economic issues. {T}his data paper presents a new coastal high resolution {S}ea {L}evel {A}nomaly ({SLA}) product, {ALTICAP} ({ALT}imetry {I}nnovative {C}oastal {A}pproach {P}roduct), derived from along track satellite altimetry. {T}o enable as many coastal applications as possible, collocated altimetric significant wave height and wind data are also provided, as well as quality flags and the geophysical corrections applied to the {SLA}. {C}overing all ocean regions between 0 and 500 km from land, and between 66 degrees {S} and 66 degrees {N}, this dataset contains 5 years ({F}ebruary 2016 to {J}uly 2021) of 20 {H}z altimetry measurements from the {J}ason-3 mission. {T}he altimetric standards and geophysical corrections used to compute the {SLA} have been selected following a round robin study based on 22 of the most recent algorithms available. {T}he processing solution adopted was a compromise between the capability of each algorithm to provide the best sea level solution over the entire strip between 0 and 200 km from the coast and a guarantee of product continuity in the future.{T}he comparison of {ALTICAP} and tide gauge {SLA} time series shows the ability of the {ALTICAP} product to capture the coastal sea level variability, with average correlation and root mean square deviation values of 0.74 and 9 cm respectively. {O}n global average, altimetry {SLA} time series remain 80 % complete up to 9 km from the coast after editing. {ALTICAP} is a global high resolution altimetry sea level product optimized for coastal applications and ensuring quality continuity up to the open ocean, directly available online. {T}he complete protocol followed during the round robin study ({B}irol et al., 2023), as well as all the results (https://www.aviso.altimetry.fr/en/data/products/sea-surface-height-products/global/altimetry-innovative-coastal-approach-product-alticap.html, last access: 26 {M}arch 2026) and the data ({LEGOS} et al., 2023, 10.24400/527896/a01-2023.020) are freely available online.},
