With the upcoming launch of the Surface Water and Ocean Topography (SWOT) satellite in 2022 and advent of submesoscale-permitting basin-scale simulations, we would like to formulate a baseline to compare the upcoming observations of submesoscale turbulence. The models we currently have in mind are summarized in the following table:
| Simulation name | Basin coverage | Resolution | Model | Institution |
|---|---|---|---|---|
| eNATL60 | North Atlantic | 1/60 | NEMO | MEOM |
| MEDWEST60 | Mediterranean | 1/60 (ensemble) | NEMO | MEOM |
| GIGATL | Atlantic | 1 km | CROCO | LOPS |
| HYCOM50 | North Atlantic | 1/50 | HYCOM | COAPS |
| llc4320 | Global | 1/48 | MITgcm | JPL |
| GEOS-MITgcm | Global (coupled) | 1/24 | MITgcm | JPL |
| ORCA36 | Global | 1/36 | NEMO | MOI |
| lNALT60 | Agulhas region | 1/60 | NEMO | GEOMAR |
| FESOM | North Atlantic | 1 km | FESOM | AWI |
| SM-telescope | North Atlantic | 600 m | ICON-O | MPI-M |
The initial four regions of study will be in the Gulf Stream (78W-68W, 30N-40N; region 1), mid-Atlantic (54W-44W, 30N-40N; region 2), Mediterranean Sea (2W-8E, 35.5N-43.5N; region 3) and the Agulhas Current (11.5E-20E, 40.5S-30.5S; region 4). The regions are shown in the figure below along with the SWOT fast-sampling-phase trajectories:
Pending on the success of these four regions, we will increase the number of regions to 10. If you would like to contribute with your dataset, please read the Consortium Agreement and reach out to us by raising an issue on Github. We are currently in the process of fluxing data to the OSN cloud storage and Jupyterhub maintained by 2i2c where collaborators involved would have access to the data and Python-based analytical tools. In order to allow for efficient cloud storage, we will ask you to provide the regional dataset in the format detailed in the Data Request.
Example notebooks of analyzing sea-surface data are given here.
