The package DIVAnd_HFRadar interpolates surface current data on a regular grid possibly taking dynamical contraints into account. The primary use-case is for radial current measurements for high-frequency radars (like WERA or CODAR SeaSonde). But it can also be applied to any other current data (like ADCPs or drifters).

The method is described in: Barth, A., Troupin, C., Reyes, E., Alvera-Azcárate, A., Beckers J.-M. and Tintoré J. (2021): Variational interpolation of high-frequency radar surface currents using DIVAnd. Ocean Dynamics, 71, 293–308 doi: 10.1007/s10236-020-01432-x (open access, bibtex)


Install DIVAnd_HFRadar.jl in julia 1.5 or later with the following command executed in Julia:

using Pkg
Pkg.add(url="https://github.com/gher-ulg/DIVAnd_HFRadar.jl", rev="master")


Documentation is available here.


A online-demo is available on the free service binder.org at the following link: Binder (this can take 2 to 10 minutes to start). If this does not work, then you can install Pluto.jl in Julia by running:

using Pkg
using Pluto

Then open the file examples/HFRadar_synthetic_case_pluto.jl
