SuperDARN data products
- Data are provided from January
2000 to the end of the Cluster mission. Convection maps are generated
even in the absence of the radar observations, so maps will be
available for very 120 s interval. The convection maps are produced
using the standard SuperDARN "map-potential" assimilation and analysis
tool. This takes radar observations and the concurrent IMF orientation
and produces an electrostatic pattern, expressed as a spherical
harmonic series expansion. We have integrated the data at 120 s cadence
and produced a fit of order 8. Also
provided are the IMF orientations used in the analysis, the number of
radars that were operating, and the number of radar observations that
were used to constrain the fit. Additional information includes the latitude at which the electrostatic potential was assumed to go to zero known
as Heppner-Maynard boundary, the difference between the maximum and
minimum in the potential, a measure of the overall convection strength.
- Images are projected onto the 40x40 grid (Solar magnetic coordinate system)
- Three sorts of quicklook
plotts are available in -png format for browsing: 1) monthly plots of
electrostatic potential along the dawn-dusk meridian, 2) day plots of
144 thumbnails of the potential pattern every 10 mins of the day, 3)
hourly plots of the potential pattern (6 panels every 10 mins)
