Bases: opendrift.readers.basereader.continuous.ContinuousReader

A continuous (in space and time) reader, able to provide exact values at any desired point (within bounds). This reader type is suitable for constant readers, analytical readers, or readers that are static and continuous within the valid domain (e.g. the landmask reader).

Reader which statistically extrapolate current forcing. It uses the residual track obtained by subtracting the wind forcing component from the past observed motion of a particle.

get_variables(requested_variables, time=None, x=None, y=None, z=None)

Obtain and return values of the requested variables at all positions (x, y, z) closest to given time.
