  • 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)
