An array of five scintillation detectors has been installed in Sharif University of Technology to record extensive air showers. By using the time lags of the secondary particles of air showers relative to each other and the location of each of these particles relative to the core of the shower, the arrival direction of the primary particle producing each air shower has been obtained.These data show that the distribution of time intervals of successive events in all directions of arrival into the atmosphere is a random distribution. The distribution of the time intervals between successive events in different seasons has also been obtained and the seasonal effect has been investigated. The effects of the environment, including temperature and pressure, on the cosmic ray count rate have been investigated. The distribution of zenith and azimuth angles, as well as the solar, sidereal, and antisidereal time distributions of cosmic rays, have been obtained.
