ECLAT Cluster boundary and region data products

The magnetosphere comprises a variety of overlapping plasma environments, which can be difficult for the non-expert to distinguish.  To enable effective usage of Cluster data by the wider scientific community, including ground-based/ionospheric and modelling communities, his data product consists of a comprehensive list of plasma regions encountered in the nightside magnetosphere using CAA Cluster data from periods 2001-2009. The regions identified are those where major energy transport/conversion processes take place, and important regions for system level science. Characteristic averaged parameters are provided for each region.  It is envisaged that this data product will act as input to event/region selection for coordinated research.  Full details can be found in the boundary and region data product user guide.

ECLAT MIRACLE products

MIRACLE networkThe Magnetometers - Ionospheric Radars - All-sky Cameras Large Experiment (MIRACLE) network provides measurements of the equivalent current distribution in the Scandinavian sector.  Equivalent current maps at 1 min cadence for the period 2001 to 2010 will be ingested into the Cluster Active Archive.

Data will be provided in Cluster Exchange Format (CEF) and a variety of quicklook formats.  Full details can be found in the Equivalent Current data user guide.

ECLAT SuperDARN products

SuperDARN Pykkvibaer radar
The SuperDARN radar located at Pykkvibaer, Iceland

The Super Dual Auroral Radar Network (SuperDARN) comprises an ever-growing number of radars which provide ionospheric convection measurements in the Northern and Southern Hemispheres at 2 min cadance.  SuperDARN observations for the period 2000 to 2010 will be ingested into the Cluster Active Archive.

Data are provided in Cluster Exchange Format (CEF) and a variety of quicklook formats.  Both CEF and quicklook data are available through the CAA and via FTP (follow SDARN, NMAP and SMAP for northern and southern hemisphere, respectively).  Full details can be found in the ECLAT SuperDARN user guide.

ECLAT IMAGE FUV products

The Imager for Magnetopause-to-Aurora Global Exploration (IMAGE) mission captured images of the polar auroras between 2000 and 2005, using the Far Ultraviolet Instrument (FUV).  IMAGE FUV summary data from the Wideband Imaging Camera (FUV/WIC) and Spectrographic Imager (FUV/SI12), providing information on electron and proton precipitation respectively, will be ingested into the CAA to provide contextual information for the Cluster mission.

The IMAGE FUV data are provided courtesy of the Principle Investigator for the IMAGE FUV instrument, Stephen Mende (University of California, Berkeley).  Full IMAGE FUV data can be found at the IMAGE Science Center or the FUV homepage.

Summary IMAGE FUV data are provided in Cluster Exchange Format (CEF) and a variety of quicklook formats.  Both CEF and quicklook data are available through the CAA or via FTP (follow IMAGE_FUV).  Full details can be found in the ECLAT IMAGE FUV data user guide

ECLAT field line tracing products

The Tsyganenko T96 and Tsyganenko and Sitnov TS05 models have been used to determine the location of the ionospheric conjugate footprint of the Cluster spacecraft.  This information is provided in Cluster Exchange Format (CEF) and as quicklook plots.  Both CEF and quicklook data are available through the CAA or and quicklook plots are available via FTP (follow FLT).  Full details can be found in the ECLAT field line tracing user guide.

ECLAT GUMICS modelling products

GUMICS example 1Even with multi-point measurements, such as provided by Cluster, the magnetosphere is a sparsely sampled system.  MHD modelling using the Grand Unified Magnetosphere Ionosphere Coupling simulation (GUMICS) provides a contextual framework within which to place the Cluster measurements, and to understand the link between in situ measurements and measurements of other parts of the system, such as the ionosphere.

ECLAT includes two main GUMICS products: "run libraries" of model outputs in reponse to different solar wind conditions; a "year-long run" in which GUMICS provides continuous output in response to the changing solar wind conditions observed in 2002.  Full details can be found in the GUMICS data product user guide.

ECLAT system level products

Open magnetosphereIn addition to detailed observations of the magnetosphere-ionosphere system, higher level indices allow characterization of magnetospheric state.  One of the key observables is the open magnetic flux content of the magnetosphere, or polar cap flux.  ECLAT provides two measures of the polar cap flux, one derived from in situ measurements of the lobe magnetic field strength, the other from the size of the ionospheric polar cap in IMAGE FUV observations.  Other characteristics derived from auroral images, such as the size, shape, and orientation of auroral boundaries are provided, as well as geomagnetic and solar wind indices.  The data will be available through the CAA; both CEF and quicklook data are available via FTP (follow AUX or IMAGE_AUX).  Details can be found in the System level product report.

ECLAT visualization tools

Visualization software for the SuperDARN, IMAGE FUV, and auxiliary datasets, written in IDL, will be available through the CAA.  The software is also available via FTP (follow software).  For full details see the SuperDARN and IMAGE FUV visualization software user guide.

ECLAT workshops

A key aspect of ECLAT are the workshops which inform the development of our data products and encourage their use.  Details of the workshops can be found on the ECLAT meetings page.
