1) Equivalent Ionospheric Currents (EICs) derived using the Spherical Elementary Currents Systems (SECS) technique at 10 sec Resolution in Geographic Coordinates maxmize
Resource ID:spase://VMO/NumericalData/SECS/Magnetometer/EICS/PT10S
Start:2007-01-01 00:00:00 Observatory:Spherical Elementary Current Systems Cadence:10 seconds
Stop:2011-01-31 23:59:59 Instrument:Spherical Elementary Current Systems Instrument Resource:NumericalData
The Equivalent Ionospheric Currents (EICs) data set contains horizontal ionospheric current data (Jx and Jy) derived using the SECS technique [Amm and Viljanen, Earth Planets Space, v. 51 pp. 431-440, 1999]. Positive Jx points to the geographic north pole. Positive Jy points to geographic east. The location of these currents is in geographic coordinates at 10s resolution. The distribution of these currents is not the same as the spherical elementary current amplitudes. The UT and date are obtained from the file name. For more information see Weygand et al. J. Geophys. Res. 116, A03305, doi:10.1029/2010JA016177, 2011.

THEMIS Ground All Sky Imager at Athabasca: 256 x 256 pixel full resolution images of auroral oval. The ASI stations monitor a 170 degree field of view imaging the auroral oval at kilometer resolution. The ASI is comprised of a fisheye lens and CCD in a stainless steel enclosure topped with a transparent acrylic dome. The CCD has a resolution of 256 x 256 pixels. Exposure control ranges from 5 s to 1 ms although the typical data rate is one image every 3 seconds. Silicone heaters keep the instrument within the nominal temperature range. During daylight hours a sun shades deploy to protect the CCD.
