The top panel shows the in situ density average when the satellite was below 470 km altitude for the whole latitudes (±13°N geographic latitude), and for only ±8° magnetic latitudes coverage (second from top panel). The bottom two panels show the zonal and meridional wind components observed by TIDI instrument onboard TIMED satellite.</table>
