Current data
The minutely pulse counting rate measurements from neutron counters of the Tien Shan 18NM64 supermonitor.

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).

Low-energy neutrons
Monitoring data of the intensity of low-energy (10-2 - 106 eV) neutron environmental background at the Tien Shan mountain station.

Atmospheric data
Measurements of the barometric pressure and air temperature in the vicinity of neutron detectors.

Tien-Shan Weather Station

Weather Data
On-line measurements of the atmospheric pressure, temperature, relative humidity, etc at the Tien-Shan mountain station.

Mean values
Averaged data on the pressure, temperature, etc for the moments of 3,9,15,21 hours of LOCAL time.

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
The basic shower characteristics: the axis position&direction, the total number of charged particles (shower size), and the "age" parameter of EAS registered by the "CENTER" shower subsystem which have been obtained through approximation of the measured particle density distributions by a set of Nishimura-Kamata-Greisen functions.
