Most energetic cosmic-ray electrons and positrons ever observed
Electrons Positrons Earth
2024/12/10
Scientists have recently identified electrons and positrons with the highest energies ever recorded on Earth. They provide evidence of cosmic processes emitting colossal amounts of energy, the origins...
基于Global Positioning System (GPS)掩星数据在平流层具有较高准确性、稳定性的优势，本文尝试用新一代GPS掩星观测——the Constellation Observing System for Meteorology, Ionosphere, and Climate (COSMIC)资料验证不同卫星平台上先进的微波探测仪（AMSU）的平流层观测结果.通过COSMIC大...

Recent particle-in-cell (PIC) simulation studies have addressed particle acceleration and magnetic field generation in relativistic astrophysical flows by plasma phase space structures. We discuss the...
COSMIC大气掩星开环数据反演方法
GPS掩星反演 开环数据处理 电波弯曲角 导航数据调制影响
2013/11/7
COSMIC星座GPS无线电掩星探测利用GPS开环接收技术提高低层大气观测数据的质量和对上升掩星事件的跟踪能力.开环掩星观测数据受到GPS导航数据调制的影响，在其数据后处理中必须消除该影响以获得高质量的科学反演结果.利用GPS导航数据调制码数据和利用开环数据本身内在的关系等两种方法可以消除该影响.将上述方法应用于COSMIC的掩星事件个例反演，获得了修复的大气附加相位数据；并利用几何光学近似反演方...
