DATASET OVERVIEW
Description(s)
Abstract
The induction magnetometer data observed at Muntinlupa, Republic of the Philippines.
The data consist of variations of three-dimensional (H, D, and Z 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. Importnat 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
