The effect of the Galactic Cosmic Ray (GCR) flux on Earth's climate is highly uncertain. Using a novel sampling approach based around observing periods of significant cloud changes, a statistically ro...
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...
Formation of large NAT particles and denitrification in polar stratosphere: possible role of cosmic rays and effect of solar activity
