Database contents of Santiago neutron monitor data starting
from December 2001 (6NM-Supermonitor). The interval of accumulation:
hourly and and 1-minute since December 2001.
An interactive access is possible to this database and FTP
Interactive access Data in this regime are
available in graphical and in digital presentation as well. All
graphical plots are given relative to "February 1987".
Access by FTP
One-minute data are in directory ftp_NM1, hourly data in
directory ftp_NM. Ground Level Enhancement (GLE) data are in the
GLE directory. One-type data are presented in their own Format:
hourly data in format C, 1-minute data in W format, and GLE data
in GLE format.
There are three types of 1-minute data: neutron
monitor data corrected for atmospheric pressure (C), atmospheric
pressure (P), and neutron monitor data uncorrected for atmospheric
Hourly data are presented uncorrected
(U) and corrected for atmospheric pressure (P).
Pressure corrected hourly data are kept as original (O)
and corrected (C).
