Description: 
Since October 1, 1957, variations in the intensity of cosmic rays 
were studied in the ionization chamber of the Tbilisi Cosmic-Ray Laboratory. 
The Laboratory also possesses a cubic telescope and a neutron monitor. The 
influence of temperature on the layers of the atmosphere, atmospheric 
pressure, the earth's magnetic field, and the influence of solar perturba- 
tions on the intensity of cosmic rays have been studied.
