SWOT ocean data products and CNES AVISO services: an overview

The Surface Water and Ocean Topography (SWOT) mission was launched in December 2022, followed by a three-month commissioning phase and a three-month Calibration and Validation (Cal/Val) phase before the SWOT spacecraft transitioned from a 1-day to a 21-day repeat orbit for science operations in July 2023. Measurements over the ocean surface from the low-rate (LR) data of the SWOT KaRIn (short for Ka-band Radar Interferometer) instrument provided striking 2D images of various ocean features at different spatial and temporal scales. These features include (but are not limited to) the evolution of (sub)mesoscale eddies in energetic currents, the propagation of ocean surface waves and internal tides, and the recent development of El Niño in the tropical Pacific Ocean.

As part of the public release of pre-validated SWOT KaRIn data for evaluation and validation, we will showcase the multiple ocean products distributed by the CNES AVISO center along with some applications for open ocean and coastal ocean studies. This contribution will also present the SWOT ocean data access and services for optimal data use from AVISO, as well as some SWOT dedicated tools provided by a common PODAAC/CNES GitHub platform.
