Database contents of MIRNY neutron monitor data starting from 2007 (12NM64-Supermonitor). The interval of accumulation: hourly and 1-minute since January 2007. Database updating goes once/day (in future it is planned in near real time). An interactive access is possible to this database and FTP as well (!).

Interactive access

Data in this regime are available both in graphical and in digital presentation. All graphical plots are given relatively 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. Each kind of data is presented in its 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 for drift or jumps (C). Corrected data (Dir C) firstly are the same as original data, but they may be corrected in future e.g. for the snow effect, for the possible long time jumps, when the sweing is required, slow drift, and, at last, cleaning data for the occasional mistakes. The special programs are inclosed in the corresponding folders to look through data in the grafical regime. They should be replaced on your computer to be used. Thus, to look through 1-minute and hourly data the program Plot_DAT or Plot_UNI may be used for hourly and minute data, and for GLE data use Plot_GLE program. After the corresponding Folder is opened by command OPEN, the following sort should be done: all type ( *.w1u, *.w1p, *.w1c) - select and plot 1-minute data, all type (*.?0u, *.?0p, *.?0o, *.?0c) - select and plot hourly data.
