INGV Preliminary Terra Nova Bay magnetic data
=============================================

.. contents:: The tiny 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 Terra Nova Bay magnetic observatory (IAGA code: TNB; Latitude: -74.693000°; Longitude: 164.099000°; Altitude: 59.000 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.
