The Dataset's Variables and Attributes

Row Type	Variable Name	Attribute Name	Data Type	Value
attribute	NC_GLOBAL	acknowledgement	String	ICATMAR HF Radar Network has been established with the support of the European Maritime and Fisheries Fund, the European Maritime, Fisheries and Aquaculture Fund and the fund provided by the Government of Catalonia. The network has been designed, implemented and managed through the efforts of the Direcció General de Política Marítima i Pesca Sostenible (Government of Catalonia) and the Insitut de Ciències del Mar (CSIC), Barcelona.

attribute	NC_GLOBAL	citation	String	These data were collected and made freely available by the EuroGOOS European HFR Node. These data were collected and made freely available by ICATMAR and the programs that contribute to it. Data was collected by the Government of Catalonia and CEFREM (France), and processed by ICATMAR with the support of the European Maritime, Fisheries and Aquaculture Fund (EMFAF) and the Climatic Funds Program of the Government of Catalonia.
attribute	NC_GLOBAL	comment	String	Total velocities are derived using least square fit that maps radial velocities measured from individual sites onto a cartesian grid. The final product is a map of the horizontal components of the ocean currents on a regular grid in the area of overlap of two or more radar stations.
