This site provides basic information about the Bartol Neutron Monitor Network as well as links to 1) discussions of recent events, 2) an explanation of how neutron monitors work, 3) instructions for downloading of data, 4) listings of personnel and points of contact, and 5) other neutron monitor sites.
Home page for yearly files of hourly average data from all Bartol Neutron Monitors containing
pressure corrected intensities, uncorrected intensities, and measured atmospheric pressure
Includes conditions for use of data and descriptions of processing level
Data are grouped into two sets of files.
Set A contains data from neutron monitors at
McMurdo: June 24, 1960 - Present
Newark: July 1, 1964 - Present
South Pole: March 1, 1964 - November 27, 2005
Thule: August 13, 1957 - Present
Set B contains data from neutron monitors at
Fort Smith: October 4, 2000 - Present
Peawanuck: September 14, 2000 - February 1, 2009
Nain: November 10, 2000 - Present
Inuvik: January 1, 2000 - Present
Direct links to yearly files are provided for viewing of one or a few years. Also provided is
a link to the ftp server where the files reside for direct downloading of from one to the total
set of yearly files. On the ftp server, the file naming convention for set A is BRIYYYY.txt. The
file naming convention for set B on the ftp site is BRIYYYYB.txt
Additional documentation concerning the specific neutron monitors included in each file is
provided at the top of each yearly file.

Fort Smith neutron monitor ground-level intensities of
cosmic-ray produced secondary neutrons, corrected for
effects of atmospheric pressure and, if necessary,
changes in normalization (see documentation in file header).
Intensity is given as counts/100 per hour.
Rigidity range (GV) refers to rigidity of primary cosmic rays
capable of producing an observable neutron shower.
Fort Smith neutron monitor ground-level cosmic ray intensities
as measured, prior to application of corrections.
Intensity is given as counts/100 per hour.
Peawanuck neutron monitor ground-level intensities of
cosmic-ray produced secondary neutrons, corrected for
effects of atmospheric pressure and, if necessary,
changes in normalization (see documentation in file header).
