ESA 4DMED-SEA - Mediterranean Sea Gridded L4 4DvarNET (1/8°) Sea Surface Heights And Derived Variables

<p>The gridded Sea Level Anomalies (SLA) presented here result from the application of the 4DVARNET algorithm, as described by <a href="https://isprs-annals.copernicus.org/articles/V-3-2021/295/2021/isprs-annals-V-3-2021-295-2021.html" target="_blank" rel="noopener">Fablet et al., 2021</a>. Here, the resolution of the dynamical model used for the learning/training (<a href="https://github.com/ocean-next/eNATL60">eNATL60-BLB02</a>) is here downgraded&nbsp;to 1/8&deg;. The algorithm takes as input Level-3 altimeter data distributed by the Copernicus Marine Service (<a href="https://doi.org/10.48670/moi-00139" target="_new">https://doi.org/10.48670/moi-00139</a>). This product provides additional variables such as Absolute Dynamic Topography and geostrophic currents (both absolute values and anomalies) at a resolution of 1/24&deg; over the Mediterranean Sea and for the period from 2016 to 2022. It is intended for delayed-time applications.</p>
