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 and atmospheric pressure, contributing data to the international NMDB network (http://www.nmdb.eu).

This service publishes daily tables containing two columns:

The timestamps reflect actual measurement times, ensuring accurate tracking even when delayed data from previous days is incorporated into current files due to communication delays with space stations.

The data is collected and provided by the Institute of Ionosphere (https://ionos.kz/).
