Table information for 'neutrons.main'

General

This table is available for ADQL queries and through the TAP endpoint.

Resource Description:

The Alma-Ata Cosmic Ray Station operates the 18NM-64 neutron supermonitor at an altitude of 3340 meters above sea level, with a geomagnetic cutoff rigidity of 6.7 GeV. The station provides real-time, minute-level measurements of cosmic ray intensity, contributing to the international NMDB network. These data support the study of cosmic ray variations and space weather phenomena.

The provided dataset consists of daily tables, where each table corresponds to a single observation day. The data includes two columns:

The data are collected and provided by the Institute of Ionosphere, (https://ionos.kz/) and are also available through the Kazakhstan Space Weather Portal (https://ssa.fai.kz/, registration required), which additionally offers interactive visualizations and graphs.
