DESCRIPTION OF THE NEUTRON MONITOR DATA SETS:

Stations specifications Data Availability  Comments  Acknowledgements

The neutron monitor data sets are the parts of the "Heliosphere" database supported by the Institute for Cosmophysical Research and Aeronomy SB RAS, Yakutsk, Russia. 
These data sets contain the 5-minute values of the neutron component of the cosmic ray intensity measured by several cosmic ray stations. Data gaps were filled with zeroes for the missing intervals.

flag = 1 - failure of the 1st section
flag = 2 - failure of the 2nd section
flag = 3 - failure of the 3d section
flag = 4 - barograph was out of operation
flag = 5 - station was out of operation
flag = 6 - data were interpolated for up to 6 hours interval of one section failure
flag = 7 - uncorrected count rate and pressure data were lost
