![]() The 18-NM-64 neutron monitor located at Alert, Northwest Territories, Canada, was unique because its asymptotic cone of acceptance in space is less than 10 degrees wide and is aligned within 7 degrees of the spin axis of the Earth. Until December 31, 1972, the station was operated and maintained by Atomic Energy of Canada Ltd., but on January 1, 1973, the National Research Council of Canada took over the responsibility for maintenance of the station. Publication of the daily rates in SGD began in January 1966 but a chart of hourly values from Deep River, described below, has been published in SGD since January 1959. The Deep River, Ontario, Canada, neutron monitor, follows the IQSY design. Hourly averages, both corrected and uncorrected and local pressure data are available in both tabular and digital form for these stations from the WDC-A for Solar-Terrestrial Physics, Boulder, CO. The publication of these data in this monthly series began September 1960 for Climax and in January 1979 for Huancayo. For a more detailed description of the neutron intensity monitors see J.A. The instruments are standard Chicago type neutron monitors, utilizing 12 BF3, counter tubes, divided into two identical and independent sections. Lentz of the Enrico Fermi Institute for Nuclear Studies, University of Chicago. The Climax, CO, USA, and Huancayo, Peru, (replaced by Haleakala, Hawaii) Neutron Monitor data are communicated by J.A. The characteristics of the stations are given below the data are corrected applying the barometric coefficients to the listed standard station pressure. 1.Ĭosmic ray neutron monitor data - daily and monthly averages from a worldwide network 1953-present -ĬOSMIC RAYS (from SGD Explanation of Data Reports)Ĭosmic Ray Tabulated Observations - The table presents the daily (UT) average counting rates per hour (scaled) for seven high counting rate neutron monitors: Thule, Deep River, Kiel, Climax, Beijing, Tokyo, and Haleakala. During these times, polar flights are generally diverted to lower latitude flight paths. These effects are especially augmented during large solar particle events. Online cosmic ray airline flight profile calculation available. ![]() The high energy particles affect airplane passengers - the FAA has an Particle Interactions with Matter website.
