CDF time name_strlen " 4 title @Data from instrument SCB-CARTHE004 on platform Drifter CARTHE004 institution KSOCIB (Sistema de Observación y predicción Costero de las Islas Baleares) netcdf_version @ Conventions CF-1.6 abstract Lagrangian experiment in the Ibiza channel during Autumn 2018, aiming to use the novel CARTHE drifters (low-cost, compact, practical, and eco-friendly) to validate HF-Radar and WMOP surface velocities, capture all representative spatio-temporal scales of surface circulation, study dispersion of surface particles and perform HFR data assimilation experiment with WMOP. Novel CARTHE drifter (low-cost, compact, practical, and eco-friendly) representative of the upper 0.60m (including Stokes drift), with minimal wave-rectification issues, with wind-induced slip velocity < 0.5% of the neutral wind speed at 10m.
