INGV geomagnetic data, GIC indices and alert: Lampedusa
=======================================================

.. contents:: Table of contents

1-minute averages of vector the variations of the components (H, D, Z) and of total intensity (F) of the Earth's geomagnetic field measured at Lampedusa magnetic observatory (IAGA code: LMP Latitude: 35.517000° Longitude: 12.545000° Altitude: 93.000 m).  In detail, preliminary pseudo H and D values (that are expressed in the instrument frame) will be used to estimate of the horizontal components (i.e. X and Y) in the NEC (North-East-Center) frame. X and Y so estimated will be then used to estimate GICx and GICy indices. These data are updated in real-time and can be retrieved from in json format from a web service so that the size of the file (estimated in the DATA DESCRIPTION TAB) actually depends on the query. Queries for a few-days data obtain a rapid reply while for longer queries (say from 1-month upward) obtain slow replies.
