Tien Shan Mountain Cosmic Ray Station

The Alma-Ata high mountain cosmic ray neutron monitor

Neutron monitor (cosmic ray station Alma-Ata B) is situated 28 km from Almaty at the mountain. It is operating in Laboratory of Geocosmical Relationships at the Institute of Ionosphere, Ministry of Education and Science.

Location of Cosmic Ray Station Alma-Ata B:

Latitude 43.2 N
Longitude 76.6 E
Altitude 3340 m above sea level
Standard pressure 675.0 mb
Geomagnetic cut-off rigidity 6.61 GV
Type 18NM-64

The Alma-Ata high mountain (3340 m) cosmic ray neutron monitor has a counting rate of 1200 c/s. The combination of its geomagnetic cut-off rigidity and high statistic is such that permits to detect and investigate solar flare particles and modulation effects of galactic cosmic rays.

Now we present hourly, minutely graphs of cosmic ray intensity and hourly data of atmospheric pressure at the station.
