SWOT East Greenland Current 2023-2024

The dataset contains gridded maps at 2 km resolution of ocean topography (ADT), geostrophic currents, and relative vorticity in the Western Nordic Seas from June 2023 to October 2024. The fields are generated at 3 hour temporal resolution, but provided here daily. The maps are derived by assimilation of SWOT and nadir altimetry data in a 1.5 layer quasi-geostrophic model using the BFN-QG algorithm (https://github.com/leguillf/BFN-QG). The product covers the ice-free ocean and the marginal sea ice zone (sea ice concentration 5%-75%). Areas with sea ice concentration >75% are masked out.A video file is also provided. It shows ADT, geostrophic currents, and relative vorticity between 1 April 2024 and 26 October 2024.
