DESCRIPTION OF THE PRODUCT
LDiñ (Local Disturbance index for Spain) is the result of the collaboration between University of Alcala and Red Eléctrica de España in their aim to study the relationship between the space weather science and their effects on vulnerable technological infrastructures. It has been derived from research conducted by the Space Weather Group at University of Alcala. The index quantifies the disturbance of the magnetic field for the Spanish territory. It makes use of the magnetic field registered at the station of the 'Real Instituto y Observatorio de la Armada' in San Fernando (SFS) which is received with a maximum delay of 15 minutes and processed for removal of the daily variation. The LDiñ is a realtime index for monitoring, diagnostics, and forecasting purposes. The procedure to obtain the LDiñ is patented in Spain and patent-pending for Europe.
