MAGnetic Data Acquisition System Database (MAGDAS-DB)

• MAGDAS (MAGnetic Data Acquisition System)
(About the MAGDAS)
• The MAGDAS project was founded by the integration of the previous three magnetometer networks: CPMN, 210MM and EMN.
• 1 sec. and 1 min. sampling geomagnetic data are obtained from August, 2005.
• The current principal investigator (PI) is Professor Akimasa Yoshikawa, but he is scheduled to be succeeded by Multiple Principal Investigators (MPIs) in 2024 or 2025.
• The new MPIs will be Dr. Shuji Abe and Professor Akimasa Yoshikawa.
• The previous PI was Professor Kiyohumi Yumoto who retired in 2012.
(Supporting Information)
• This MAGDAS observation was supported by Japan Society for the Promotion of Science (JSPS) KAKENHI grant number 15253005, 18253005,188068, 198055 and 208043.


• MAGDAS INDICES
The scientific products from MAGDAS data for space weather research.


• The CRUX project
(About the CRUX)
• We have installed fluxgate magnetometers, an induction magnetometer and an all-sky aurora imager in New Zealand and are conducting geomagnetic and aurora observations.
• 1 sec. sampling geomagnetic data are obtained from March, 2011.
• The PI of magnetic field observations is Dr. Yuki Obana.
• The PI of aurora observation is Professor Keisuke Hosokawa.
(Supporting Information)
• This work was carried out by the joint research program of the Institute for Space-Earth Environmental Research, Nagoya University.
• This observation was supported by JSPS KAKENHI Grant Number 24740333 and 19H01958.


• FM-CW raders
We operate a Frequency-Modulated Continuous-Wave radar that can estimate the ionosphere's altitude, travel speed, and ionospheric electric field.
