DATASET OVERVIEW
Description(s)
Abstract
The induction magnetometer data observed at Cangar, Indonesia. The data consist of
variations of two-dimensional (H and D components) geomagnetic field taken with a
sampling rate of 64 Hz, and some engineering parameters for the instrument, such as
the sensitivity and phase difference. The digital data are distributed in the Common
Data Format (CDF) through the ERG-SC repository. Important Notes: 1. For frequencies
below ~1Hz, use the following equation to obtain amplitude values in units of nT/s:
dB/dt (nT/s) = data (V) / quick_sensitivity. The value of quick_sensitivity is given
in global attributes. For frequencies above ~1Hz, use the exact sensitivity curve
to obtain absolute amplitude of waves. 2. Please note that the positive direction
(polarity) of H, D, and Z are different depending on the station. For example, in
February 2011, the polarity is GAK: positive=northward, eastward, upward; MGD: positive=northward,
eastward, downward; ATH: positive=northward, eastward, downward; MSR: positive=southward,
westward, upward; STA: positive=northward, eastward, downward. Please see http://stdb2.isee.nagoya-u.ac.jp/magne/magne_stations.html
