This example runs an OceanDrift simulation with current data from CMEMS To run this example, you need a CMEMS account created at with username and password stored in a .netrc file with contents:

machine copernicusmarine login <your username> password <your password>

This file must be stored in your home folder (and unreadable by others) or in the main OpenDrift folder

Alternatively, an Xarray dataset can be created explicitly with the copernicusmarine client, and provided to reader_netCDF_CF_generic:

from datetime import datetime, timedelta
from opendrift.models.oceandrift import OceanDrift

lon = 4.8; lat = 60  # Bergen, Norway
lon = -89; lat = 29.8  # New Orleans
lon = 107; lat = 10  # Ho Chi Minh
lon = 123; lat = -16.3  # Australia

o = OceanDrift()


o.seed_elements(lon=lon, lat=lat, number=5000, radius=1000, time=datetime.utcnow())

o.animation(fast=True, clabel='Ocean current [m/s]',
            background=['x_sea_water_velocity', 'y_sea_water_velocity'])
