  10 + <Description>MARSIS is a low frequency, nadir-looking pulse limited radar sounder
  11 + and altimeter with ground penetration capabilities, which uses synthetic aperture techniques and a secondary receiving antenna to isolate subsurface reflections.
  12 +
  13 + The operation altitudes for MARSIS are up to 800 km above the Martian surface for subsurface sounding and up to 1200 km for ionospheric sounding.
  14 + In its standard operating mode, the instrument is capable of making measurements in 1 MHz wide bands centred at 1.8, 3.0, 4.0 and 5.0 MHz
  15 +
  16 + This data set contains Total Electron Count data from the MARSIS subsurface sounder on Mars Express. Useful information can be found in the peer-reviewed article:
  17 + Correction of the ionospheric distortion on the MARSIS surface
  18 + sounding echoes, by Mouginot et al., Planetary and Space Science, Volume 56, Issue 7, p. 917-926, 2008</Description>

  9 + <Description>The level 5 TEC data are derived following a method described in
  10 + details by Mouginot et al. Planetary Space Science, V56, 2008.
  11 + The correction method consists in finding the three parameters [ a1 ; a2 ; a3 ]
  12 + defining the signal distortion phase Δφ induced by the ionosphere.
  13 + In the time domain, the ionosphere distortion generates a delay and a spreading
  14 + of the radar pulse. It is clearly visible on MARSIS radargram without correction.
  15 + A by-product of the ionospheric correction is the TEC, that can be easily obtained
  16 + from the [ a1 ; a2 ; a3 ] parameters. [ a1 ; a2 ; a3 ] are
  17 + investigated in ordrer to get Δφ with the best SNR As initial conditions for this
  18 + optimization, we use the parameters fitting with a simplified Gaussian
  19 + density-profile of the ionosphere.
  20 +Then the optimization is done by using the following constraints:
  21 + * A constraint on the vertical position of the surface echo estimated with the digital elevation model MOLA.
  22 + * A constraint on the SNR. The signal amplitude must be maximal after correction.
