Fig. 8From: Geomagnetic activity dependence and dawn-dusk asymmetry of thermospheric winds from 9-year measurements with a Fabry–Perot interferometer in Tromsø, NorwayTime series of a meridional and b zonal components of the quiet-time wind (blue) derived in this study along with quiet-time HWM-modeled winds (black) and mean FPI-measured wind for Kp < 3 (green). The vertical bar represents ± 1 statistical standard deviation for individual valuesBack to article page
