Cosmic Rays
Intensity measurements of the high energy cosmic ray hadronic component (>109 eV) with a 1-min time resolution by the neutron monitor installations placed at the Tien-Shan Mountain Station (3340 m above the sea level), at the Intermediate Station (1750 m a.s.l.), in Kazakh National University (850 m a.s.l), and by the Underground neutron monitor of the Tien-Shan station (3340 m a.s.l. + 2000 g/cm2 of the rock soil).

Subsonics
Continuous 1-sec resolution measurements of the high-frequency atmospheric pressure oscillations (subsonics) made with a high-sensitive digital barograph at the Tien-Shan mountain station.

Acoustic sensor
Acoustic noise measurements with a sesitive microphone installed in a bore hole 50 m underneath the surface.

Extensive Air Showers: the "CENTER" installation

EAS characteristics
