Database contents of Inuvik neutron monitor data worked from 1964 (18NM64). The interval of accumulation: hourly from 1964; besides, 1-minute data from 1998. 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).
