INGV geomagnetic alert: L’Aquila

From both components of GIC index for L’Aquila observatory it is possible to calculate an alert based on a risk scale that associates GIC index to the probability to observe damages to the power network. At present sample files are not available since so far this kind of computation has been performed all within a peculiar software environment (IgorPro), anyway if data were stored in txt files they would be arranged in 3-columns (1-minute data)

This tableset contains a set of data corresponding to products with ids 8, 47 and 48. In detail it contains the definitive values of the X,Y and Z components (in NEC coordinates) and of total intensity F of the geomagnetic field recorded at ground magnetic observatories managed by INGV. Besides, it contains the values of the GicX and GicY indices calculated from the Y and X components, respectively. To finish it contains values of the risk (i.e. alertX and alertY) , corresponding to the estimated values of the GicX and GicY indices. Data sampling is of 1-minute.
