Cosmic Rays and Earth


Book Description

This book summarizes the results from the detection of cosmic rays at the surface and in the lower atmosphere of Earth during the fifty years since the invention of the neutron monitor by John A. Simpson in 1948. The properties of solar and galactic cosmic rays in the heliosphere, such as Forbush decreases, modulations by solar and heliosphere parameters, the physical processes that govern them, and their connection to Space Weather, are reviewed. This interdisciplinary compilation provides links between cosmic ray physics, geophysics, terrestrial climate, and human activity and health.




Sources and Availability of IQSY Data


Book Description

December 31, 1965, brought to a close the International Years of the Quiet Sun (IQSY 1964-1965). The rich harvest of scientific results produced by this intensive study of the vast region between the sun and the earth is published in a series of 7 volumes, under the general title of "Annals of the IQSY." The General Editorial Board for this project consists of 19 distinguished scientists gathered from 10 countries, with Professor W. J. G. Beynon as Chairman and Dr. C. M. Minnis as General Editor.The IQSY was sponsored by the International Council of Scientific Unions. Its geophysical and solar observations were carried out by scientists in more than 70 countries. Since the dates of the IQSY were chosen to coincide with the period of minimum activity in the 11-year solar cycle, the results obtained form a complement and counterpart to those obtained in the International Geophysical Year (IGY 1957-1958), when the sun was in the most agitated state ever observed.
