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.
