MAGnetic Data Acqusition System/Circum-pan Pacific Magnetometer Network Data
1. Name of Database: MAGnetic Data Acqusition System/Circum-pan Pacific Magnetometer Network Data
2. Institution: Space Environment Research Center, Kyushu University
3. Contents of Database:
MAGDAS (Magnetic Data Acquisition System) data are obtained from the Circum-pan Pacific Magnetometer
Network (CPMN) during the CAWSES period (2003 -2008). Magnetometers of the CPMN were installed at 50
stations all over the world during the STEP period, which are along the 210 degree magnetic meridian
including East Asia, Pacific Ocean and Micronesian Islands, and South America and Africa at the
different longitudes. The MAGDAS data consist from 3 components of the magnetic variations (H, D, Z)
with 1-second sampling rate. Users can see summary plots by WWW, and get 1-sec digital data by request
to PI (K. Yumoto). This database is very useful for investigations of the Earth Magnetism and
Solar-Terrestrial Physics in term of a global disturbance of the magnetic field on the ground.

6. Public Offering of Database:
The MAGDAS data can be provided for all the scientific purpose. Users can see summary plots
of 1day stack plot for all the stations and monthly plot for each station by WWW
http://denji102.geo.kyushu-u.ac.jp/denji/obs/cpmn/cpmn_obs_e.html
If users need the digital data for their computational analysis, we can provide the 1-sec or 1-min
digital data by request to PI (K. Yumoto; yumoto[AT]geo.kyushu-u.ac.jp) for collaborative works.
