  • Mesoscale ocean eddies are ubiquitous coherent rotating structures of water with radial scales on the order of 100 kilometers. Eddies play a key role in the transport and mixing of momentum and tracers across the World Ocean. We present a global daily mesoscale ocean eddy dataset that contains ~45 million mesoscale features and 3.3 million eddy trajectories that persist at least two days as identified in the AVISO dataset over a period of 1993–2014. This dataset, along with the open-source eddy identification software, extract eddies with any parameters (minimum size, lifetime, etc.), to study global eddy properties and dynamics, and to empirically estimate the impact eddies have on mass or heat transport. Furthermore, our open-source software may be used to identify mesoscale features in model simulations and compare them to observed features. Finally, this dataset can be used to study the interaction between mesoscale ocean eddies and other components of the Earth System.
  • Global mesoscale ocean eddy featuresA database of ocean eddies identified in daily satellite altimeter data. Each file contains the eddy features identified on that day. Each day has two file one for cyclonic and another for anticyclonic eddies. Each eddy object contains geographical and physical information as well as the grid cells that make up the eddy's body.eddies.zipGlobal daily eddy trajectoriesUsing the eddies found in our eddy database, we generated trajectories for eddies that had at least 1cm amplitude and 9 grid cells in size. This is just an example eddy trajectories dataset and researchers can filter our eddy database to construct eddy trajectories that meet their needstracks.txttracks_readme.txt
