Ionospheric single crest events at different altitudes and activity levels observed by Swarm constellation

Ionospheric plasma density variations observed at Mars by MAVEN/LPW

We report on initial observations made by the Langmuir Probe and Waves relaxation sounding experiment on board the NASA Mars Atmosphere and Volatile EvolutioN (MAVEN) mission. These measurements yield the ionospheric thermal plasma density, and we use these data here for an initial survey of its variability. Studying orbit-to-orbit variations, we show that the relative variability of the ionosp...

an investigation of accuracy and complexity across different proficiency levels in written narrative task

abstract this quasi-experimental study was aimed at examining the impact of storyline complexity on the grammatical accuracy and complexity of advanced and intermediate efl learners. a total of 65 advanced and intermediate efl learners were selected from iran language institute (ili). an intact group including 35 intermediate participants and another intact group with 30 advanced participants ...

Simultaneous observations at dierent altitudes of ionospheric backscatter in the eastward electrojet

A common feature of evening near-range ionospheric backscatter in the CUTLASS Iceland radar ®eld of view is two parallel, approximately L-shellaligned regions of westward ̄ow which are attributed to irregularities in the auroral eastward electrojet region of the ionosphere. These backscatter channels are separated by approximately 100±200 km in range. The orientation of the CUTLASS Iceland rada...

Low-latitude ionospheric turbulence observed by Aureol-3 satellite

Using PSD (Power Spectral Density) data on electron density and electric field variations observed on board Aureol-3 satellite at low-to-mid-latitude ionosphere we analyze a scale distribution of the ionospheric turbulence in a form k , where k is the wave number and α is the spectral index. At first, high-resolution data in the near-equator region for several orbits have been processed. In thi...
