Copernicus marine client | ||
======================== | ||
This example runs an OceanDrift simulation | ||

To run this example, you need a CMEMS account created at | ||
https://marine.copernicus.eu | ||
and the copernicus_marine_client installed from | ||
https://pypi.org/project/copernicus-marine-client/ | ||
