The first campaign of the ERG (Arase) - ground coordinated observations in March - April, 2017.

 The Arase (ERG) satellite was launched at 20:00 (JST) on December 20, 2016 from Uchinoura Space Center, JAXA with an ellipse orbit (perigee: 320 km, apogee: 33,200 km, and period: 580 min). All the instruments of the Arase satellite has been recently operated and measure DC electric and magnetic field variations, plasma waves and energetic particles in the inner magnetosphere.
 In the first campaign observation, we operate various kinds of ground-based instruments such as the EISCAT radar, all-sky camera, EMCCD camera, induction magnetometer, riometer and related instruments near the footprint of the orbit of the Arase satellite in order to clarify the generation and loss mechanisms of high-energetic particles in Geospace and magnetosphere-ionosphere-termosphere coupling process during geomagnetic storms and substorms.
 Detailed information of this campaign:
 Schedule and main ground-based collaborators:

  3, 2017/03/25 00:50-01:45UT, Tromso (Norway), EISCAT.
  4, 2017/03/26 23:17-26:35UT, Tromso (Norway), PWING and PSA.
  5, 2017/03/28 13:38-14:10UT, Gakona (Alaska), PWING and PSA.
  6, 2017/03/28 22:34-27:15UT, Tromso (Norway), EISCAT.
  7, 2017/03/30 12:28-14:56UT, Gakona (Alaska), PWING and PSA.
  8, 2017/03/31 00:00-03:30UT, Tromso (Norway), EISCAT.
 Our IUGONET team has collected the Quick-Look images of the campaign observations taken by various kinds of ground-based instruments, and registered the metadata to IUGONET Type-A. Now, you can easily and immediately see these Quick-Look images from this site. Please check it!

PWING Data Come, 10 Feb. 2017.

 PWING (Study of dynamical variation of particles and waves in the inner magnetosphere using ground-based network observations) is the project to aiming at future secure/safe space use by understanding the particle acceleration and loss in the inner magnetosphere.
 This project has been conducted by Prof. Kazuo Shiokawa, Institute for Space-Earth Environmental Research (ISEE), Nagoya University, and promotes a study of temporal and spatial distributions of energetic particles and ELF-VLF plasma waves in the inner magnetosphere by installing the five ground-based instruments in the sub-auroral to auroral regions with the same longitudinal intervals.
 Details of the PWING project are described on the PWING web site ( If you want to know information of the PWING instruments and data, please see the metadata of each dataset and read carefully them.
 Our IUGONET system team collaborate with PWING project, and we produce the function to compare the plots of all observatories and instruments of PWING by 1-click. This page also has a 'page-a-day viewing' function. It is easy to check PWING data.


Captions about tplot_name, 24 Jan. 2017.

 We added captions about tplot_name on UDAS web to choose variables easier.
Sample Screen:
 UDAS web is the interactive plot tool available on web browser (for PC, Smart Phone, Tablet and more), with no installation required. Tplot-names consists of technical terms, but the caption makes it easy to choose variables.
 To start UDAS web is 2 ways:
  - On search result page, choose dataset and click [Create] button
  - On detail page, click [UDAS web] banner
 It would be nice if you could use UDAS web with feel free. Thank you.

Open IUGONET Type-A, 1 Nov. 2016.

 New IUGONET System 'IUGONET Type-A' Opened. The new functions are
  - Search Data using List/Map
  - Combination Search using List/QLs
  - Show Data Information with Quick Image/Plot
  - Show How to Plot
  - UDAS web (Web-Based Interactive Tool to Create Plot)

 We will continue the development on the basis of the opinion of uses. Thank you.

IUGONET Type-A demonstration in SGEPSS fall meeting 2016

20-22 November 2016
Kyushu University, Fukuoka, Japan

The Society of Geomagnetism and Earth, Planetary and Space Sciences (SGEPSS) is an academic society for contributing to progress in science and technology associated with geomagnetism, as well as Earth, planetary and space sciences. We will demonstrate new IUGONET system "IUGONET Type-A" in SGEPSS fall meeting 2016, held at Fukuoka, Japan. We are looking forward to seeing you (This is a collaborative work with Exelis Visual Information Solutions, Inc.).
