The Federal Aviation Administration’s Civil Aerospace Medical Institute Aeromedical Research Division has operated an advisory Solar Radiation Alert System (SRAS) since 2002. This report describes the third and latest significant upgrade of the system software, known as Maps of Ionizing Radiation in the Atmosphere or MIRA. While retaining all the expected standard outputs from SRAS and its most recent successor, the Enhanced SRAS (ESRAS), the revisions include a complete conversion to using CARI-7 for calculations of solar and galactic cosmic radiation dose rates, an extension of standard output to a vertical cutoff rigidity of 15 GV, and the development of a new capability to automate e-mailing of alert messages and related files to potential users
This report presents the solar and galactic cosmic radiation models, solar modulation algorithms, and data used by CARI (i.e., the Civil Aviation Rese...
Primary cosmic radiation from both the Sun and interstellar space enters Earth's atmosphere in varying amounts. Outside of Earth's atmosphere, cosmic ...
