Vieira Ciencias de la Tierra Ionosphere electron density rocket observations ionospheric electric field On 18 December, 1995 at 21:17 hrs (LT) an electric field double probe, a Langmuir probe, and a High Frequency Capacitanceprobe were flown from the equatorial rocket launching station Alcantara (2.31°S; 44.4°W) in Brazil on board a BrazilianSONDA III rocket, for measurements of the height variation of the ionospheric electric field and electron density. The rocketreached an apogee altitude of 557 km and covered a horizontal range of 589 km. Ground equipment monitored the ionosphericconditions during the launch. The rocket passed through several medium-scale plasma bubbles mainly during the downleg. Theupleg electron density profile showed a clearly-defined base for the F-region around 300 km, while the downleg profile showed awide spectrum of electric field and electron density irregularities in this height region as well as in the upper F-region. Spectralanalysis of the fluctuations in electron density and electric field clearly indicated sharp spectral peaks at several heights, in mostcases associated with each other. This is suggestive of the electrostatic nature of these E-field waves, that may be excited at theonset of plasma instabilities along with waves in electron density. 2004 artículo científico 0016-7169 https://www.redalyc.org/articulo.oa?id=56843204 en http://www.redalyc.org/revista.oa?id=568 Geofísica Internacional application/pdf Universidad Nacional Autónoma de México Geofísica Internacional (México) Num.2 Vol.43 |
