SSCWeb 3-D Orbit Viewer

The Satellite Situation Center (SSCWeb) Systems and Services provides this application, known as TIPSOD, which can display a interactive 3-D animation of the orbits for selected spacecraft(s) and time ranges of interest.


The Coordinated Data Analysis Web (CDAWeb) services allow a software developer to use CDA software in their own applications, or general users to use the existing web interface to view and/or download data.

Magnetopause Crossing Database - GIFWALK

GIFWALK, is a service of the CDAWeb hosting the Magnetopause Crossing Database for THEMIS probes. It allows quick browsing through the magnetopause crossing events and download of a range of specialized plots and data.

UCLA Spherical Elementary Currents

The UCLA spherical elementary currents web page indicates intervals when spherical elementary currents are available and who to contact for this data. The currents have been derived from the THEMIS, CARISMA, CANMOS, GIMA, MACCS, USGS, and Greenland ground magnetometer arrays and using the method outlined in Amm and Viljanen [1999].
A subset of these spherical elementary currents are available at the Virtual Magnetospheric Observatory:

SuperMAG: The Global Ground Based Magnetometer Initiative

SuperMAG is a worldwide collaboration of organizations and national agencies that currently operate more than 300 ground based magnetometers. SuperMAG provides easy access to validated ground magnetic field perturbations in the same coordinate system, identical time resolution and with a common baseline removal approach.

Inter-university Upper atmosphere Global Observation NETwork (IUGONET)

The IUGONET project provides a plug-in software of TDAS, "UDAS", that can load and analyze ground-based observational data (e.g., geomagnetic indices, magnetometer network data, and some kinds of radar data) distributed by five Japanese institutes and universities (Tohoku Univ., Nagoya Univ., Kyoto Univ., Kyushu Univ., and NIPR).

Energization and Radiation in Geospace (ERG)

The ERG (Energization and Radiation in Geospace) project is a mission to elucidate acceleration and loss mechanisms of relativistic electrons around Earth during geospace storms. The project consists of the ERG satellite, ground-based network observation, and simulation/modeling/theory teams. The ERG Plug-in tool includes IDL libraries to load 210MM magnetometer CDF files provided by Kyushu University, STEL, Nagoya University, induction magnetometer CDF files provided by STEL, Nagoya University, and common time fitacf data of SuperDARN radars. ERG-Science Center would like to acknowledge the close working relationship between the ERG project and the SuperDARN project.

3DView Multi-Mission Tool

The EU-funded 3DView Multi-Mission tool can be used to view and manipulate THEMIS and ARTEMIS data in 4 dimensions for easier visualization, as well as including models of the Earth's magnetosphere.

MIST Survey Plots and Conjunctions

The Virginia Tech Magnetosphere-Ionosphere Science Team (MIST) and the National Space Institute at the Technical University of Denmark (DTU Space) are pleased to announce several new survey plots for inter-hemispheric comparisons of magnetic perturbations: 24 hour intervals and shorter THEMIS/MMS satellite conjunction intervals. Virginia Tech magnetometers are deployed at locations corresponding to the southern hemisphere IGRF footpoints of DTU Space magnetometers. 24 hour survey plots show how magnetic perturbation properties vary between hemispheres due to variations in ionospheric conductivity, interplanetary shock impact angle, ion foreshock location, distorted magnetic field topology, etc. Satellite survey plots show similar information during shorter periods when the THEMIS or MMS satellites are magnetically conjugate to Antarctic stations. These plots include satellite plasma and magnetic field measurements for additional context on magnetopause location, etc.


The Swarm-Aurora project was designed to facilitated and drive the use of Swarm in auroral science and build a bridge between Swarm data, the Swarm science community, and optical images of the aurora collected primarily by ground-based All-Sky Imagers (ASIs). Researchers can easily identify Swarm overflights of ASIs that were capturing images of aurora of interest, relating the electric and magnetic fields observed by the satellite to the aurora structures and dynamics as captured by the ASI. Researchers will be able to quickly scan through years of data within minutes, quickly identifying events that meet their specific research goals.
