Database contents of Irkutsk neutron monitor data starting from 1981: Hourly data up from January 1981 (6NM - Supermonitor). The interval of accumulation: hourly from 1981; besides, 5-minute data (from January 1981 - June 2004) and 1-minute since September 2004. Database updating goes in real time. An interactive access is possible to this database and FTP as well.

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 pressure (U). Hourly data are presented uncorrected (U) and corrected for atmospheric pressure (P). Pressure corrected hourly data are kept as original (O) and corrected (C).
