Interests • Couplingofatmosphericlayers due towaves? • What can we“see“ at different altitudes (and how is it related) ? • Combinationof different datasets: • Temperatures • RO (from CHAMP to COSMIC) • Saber • Electrondensityprofilesand TEC data • RO • In-situ (electron) densityandwinds at orbithights • CHAMP, SWARM SWARM (electron) densities andwinds CHAMP RO electrondensities Saber temperatures RO temperatures SWARM SPP workshop, Potsdam, 3-4 July 2014
