NSWP: High Frequency (HF) Doppler Radar for Low Latitude Studies

在Jicamarca秘鲁非相干散射雷达设施安装了一台多普勒高频雷达，目的是弄清导致赤道等离子体泡出现的过程，从而使穿越电离层的无线电信号，包括全球定位系统信号发生振荡。 的频谱和传播的电离层扰动的F-区域峰值以下的特点，并确定它们的关系，在Jicamarca观测到的EPBs。 在增强的离子密度之前的中性风逆转的垂直离子漂移的变异性确定在太阳极小期条件下，和赤道等离子体气泡发病的变异性的关系被确定。 中性风在多大程度上调制EPBs的发生，并可能推翻其他有效的触发机制也评估使用附近的法布里-珀罗干涉仪的数据。 F区电离层峰值以下的等离子体扰动，垂直离子漂移的变化，中性风，和EPB发病之间的确定的关系，最后用于在试图预测EPB的产生，沿着与相关的无线电振荡。

A Doppler High Frequency (HF) radar is placed at the Jicamarca Peru Incoherent Scatter Radar Facility for the purpose of untangling the processes that lead to the onset of equatorial plasma bubbles (EPBs), and in turn to scintillations of radio signals traversing the ionosphere, including GPS signals. The spectra and propagation of ionospheric perturbations just below the F-region peak are characterized, and their relationship to EPBs observed at Jicamarca is determined. The variability of vertical ion drift in the enhanced ion density preceding the neutral wind reversal is determined during solar minimum conditions, and the relationship of that variability to equatorial plasma bubble onset is determined. The extent to which neutral winds modulate the occurrence of EPBs, and possibly override otherwise effective triggering mechanisms is also evaluated using data from nearby Fabry-Perot interferometers. The determined relationships between plasma perturbations below the F-region ionospheric peak, variability of the vertical ion drift, the neutral wind, and EPB onset are finally used to in an attempt to predict EPB generation, along with associated radio scintillations.
