Ocean tide and loading altimetric corrections computed - with SIROCCO Tools : https://sirocco.obs-mip.fr/other-tools/prepost-processing/comodo-tools - from FES2014 atlases : https://doi.org/10.6096/3001 - for all altimetric missions. Validation available at ftp://ftp.legos.obs-mip.fr/pub/ecola/FES2014/CTOH/2021-02-diff-libfes-tools.pdf

The mean and time-varying position of the main Southern Ocean polar fronts has been calculated from a combination of gridded altimetric sea level anomalies and a new climatology of mean sea level constructed from historical data and ARGO T / S profiles.

Climatology of near-inertial currents. Global climatology of near-inertial current characteristics from satellite-tracked drifters. Data analysed : 8500 near-surface satellite-tracked drifter trajectories with drogues attached at 15 m depth.

GDR L2 from US Navy augmented by CTOH with new corrections or parameters

GDR L2 from ESA Baseline-C converted by CTOH into netCDF, splited by ascending/descending pass and augmented of recent corrections

Produit de hauteurs de mer destiné à l’étude de 23 régions côtières, avec des données le long de la trace projetées sur la trace de référence avec un intervalle d'environ 6-7 km entre les points (1 seconde). Concerne les missions Topex/Jason-1/Jason-2/Jason-3 (+Topex Interleaved orbit (TPN)/Jason-1 Interleaved orbit (J1N)), SARAL/AltiKa, Envisat, Geosat Follow On. Un traitement spécifique (développé au LEGOS) a été appliqué en appliquant les dernières corrections disponibles.

Global climatology of near-inertial current characteristics from satellite-tracked drifters. Data analyzed: 8500 near-surface satellite-tracked drifter trajectories with drogues attached at 15 m depth. Gridded map with annual and seasonnal spans.
