Advanced Composition Explorer (ACE) Real-time Solar Wind change on January 12, 2015
WEB address: http://www.swpc.noaa.gov/products/ace-real-time-solar-wind

Provider: © NASA

ACE launched on August 25, 1997. ACE spacecraft carrying six high-resolution sensors and three monitoring instruments samples low-energy particles of solar origin and high-energy galactic particles.

ACE orbits the L1 libration point which is a point of Earth-Sun gravitational equilibrium about 1.5 million km from Earth and 148.5 million km from the Sun. From its location at L1 ACE has a prime view of the solar wind, interplanetary magnetic field and higher energy particles accelerated by the Sun.

ACE also provides near-real-time 24/7 continuous coverage of solar wind parameters and solar energetic particle intensities. When reporting space weather ACE provides an advance warning (about one hour) of geomagnetic storms.

SWPC issues warnings of imminent geomagnetic storms using ACE data.


Time History of Events and Macroscale Interactions during Substorms (THEMIS)
WEB address: http://www.nasa.gov/mission_pages/themis/main/

Provider: © NASA

Over six years in space (Launch Date: Feb. 17, 2007), five spacecraft from the THEMIS mission have helped map out the magnetosphere and Aurora and improve our ability to predict dynamic space weather events.

Instruments: Electric Field Instruments (EFI); Flux Gate Magnetometer (FGM);
Search Coil Magnetometers (SCM) measures low frequency magnetic field fluctuations and waves in three directions;
Electrostatic Analyzer (ESA) -thermal electrons and ions to identify and track high-speed flows through the magnetotail and identify pressure pulses;
Solid State Telescope (SST) - particle distribution functions.

GROUND BASED INSTRUMENTS: All-Sky Imager (ASI) Array; Magnetometer (GMAG) Array;


Van Allen Probes

Provider: © NASA

Since their launch on Aug. 30 2012, the two Van Allen Probes have orbited the Earth, sampling the harsh radiation belt environment where major space weather activity occurs

The two spacecraft are measuring the particles, magnetic and electric fields, and waves that fill geospace. Only with two spacecraft taking identical measurements, and following the same path, can scientists begin to understand how the belts change in both space and time.


Ground-based instruments:

Array for Broadband Observations of VLF/ELF Emissions (ABOVE)
WEB address: http://www.ucalgary.ca/above/

Provider: © University of Calgary

Funded by the Canada Foundation for Innovation and Alberta Enterprise and Advanced Education.

ABOVE is the Array for Broadband Observations of VLF/ELF Emissions. It is a project led by researchers at the University of Calgary to deploy an array of sensitive radio receivers across Western Canada, together with systems for delivering digital data from those instruments.

The instruments are sensitive to electromagnetic waves in the frequency range from 100 Hz to 75 kHz, covering the Extremely Low Frequency (ELF) and Very Low Frequency (VLF) bands of the radio spectrum. Data from these instruments will be used to monitor the environment in near-Earth space, in collaboration with Canadian and international space missions and ground-based projects.

The instruments are currently under development at the University of Calgary. Deployment is commencing during the summer of 2013, and the full array is expected to be deployed by the end of summer 2014.


Canadian Array for Realtime Investigations of Magnetic Activity (CARISMA)
WEB address: http://www.carisma.ca/

Provider: © University of Alberta

Funded by the Canadian Geospace Monitoring (CGSM) project.

CARISMA is the continuation and expansion of an original magnetometer array that was part of the CANOPUS ground based instrumentation array. The CARISMA network is an array of magnetometers to measure disturbances in the Earth's magnetic field, caused by activity occurring in a region of space near the Earth, known as the magnetosphere. By using a distributed array of magnetometers, more information can be calculated about their time and spatial evolution.

The CARISMA array spans a range of longitude from Dawson City, YK (near the Alaska border, 220.890E) to Rankin Inlet, NU (267.890E) and a range of latitude from Taloyoak, NU (69.540N) to Osakis, MN, USA (45.870N). Currently most of these sites are on a North-South meridian known as the 'Churchill Line'. By arranging the magnetometers in this way, it is possible to investigate the radial propagation of events, because the field measured at higher latitudes is affected by regions further from the Earth than those measured at lower latitudes.

In order to properly interpret in-situ satellite data the global state of the magnetosphere must be known, as satellites make only a point measurement that needs a context. CARISMA can provide this information enabling coordinated studies with satellite measurements to performed; this is a particularly important with projects such as the THEMIS mission, and the Van Allen Probes (RBSP) mission.


Antarctic-Arctic Radiation-belt (Dynamic) Deposition - VLF Atmospheric Research Konsortium (AARDDVARK)
WEB address: http://www.physics.otago.ac.nz/space/AARDDVARK_homepage.htm

Provider: ©

The Antarctic-Arctic Radiation-belt (Dynamic) Deposition - VLF Atmospheric Research Konsortium (AARDDVARK) provides continuous long-range observations of the lower-ionosphere. The Konsortia sensors detect changes in ionisation levels from ~30-85 km altitude, with the goal of increasing the understanding of energy coupling between the Earth's atmosphere, Sun, and Space. We use the upper atmosphere as a gigantic energetic particle detector to observe and understand changing energy flows; this Science area impacts our knowledge of global change, communications, and navigation. The joint NZ-UK Antarctic-Arctic Radiation-belt (Dynamic) Deposition - VLF Atmospheric Research Konsortia (AARDDVARK) is a new extension of a well-establish experimental technique, allowing long-range probing of ionisation changes at comparatively low altitudes. Most other instruments which can probe the same altitudes are limited to essentially overhead measurements. At this stage AARDDVARK is essentially unique, as similar systems are only deployed at a regional level.


Global Riometer Array - GloRiA
WEB address: http://spears.lancs.ac.uk/gloria/

Provider: © Lancaster University

The Global Riometer Array or GloRiA project is an attempt to unite the different riometry groups around the world (and their riometers) to provide a global overview of STP events. By providing a global overview of STP processes we will be in a better position to understand them.

The GloRiA project has only just started. The first study is a global analysis of the Bastille Day polar cap absorption event.
