Galactic Cosmic Ray Modulation Studies at High Rigidities

研究人员将努力了解日光层在两个磁（黑尔）周期内由于太阳的各种刺激而发生的变化。主要工作利用了全球中子和μ子探测器网络获得的数据，其银河宇宙射线响应刚度中值为11至330千兆伏。这项研究将测试不同的宇宙射线在湍流日光层磁场中传输模型的适用性限度。它还将侧重于开发一种技术，用于预先预测太阳黑子的数量和宇宙射线的通量。对这些现象的预测对于国家空间气象方案十分重要，并且与研究太阳变率作为十年和世纪时间尺度上陆地气候变化的驱动因素有关。

The investigator will work to understand changes in the heliosphere due to various stimuli from the Sun, over two magnetic (Hale) cycles. The main effort utilizes data obtained with the global network of neutron and muon detectors with median galactic cosmic ray response rigidity from 11 to 330 gigavolts. The investigation will test the limit of applicability of different models of cosmic ray transport in the turbulent heliospheric magnetic field. It will also focus on development of a technique for advance prediction of the number of sunspots and the flux of cosmic rays. Prediction of these phenomena is important for the National Space Weather Program, and is relevant to the study of solar variability as a driver of terrestrial climate change on decadal and century time scales.
