Lead-free Neutron Monitor operating at High Altitude Research Laboratory, Gulmarg has been utilized to detect MeV energy neutron bursts produced in the lightning discharge channels. The experiment provided the first experimental evidence of neutron production in the lightning discharges. The neutrons were recorded in predetermined time interval of 320 microseconds after the detection of the f ... More

We present a physical model to calculate cosmic ray induced ionization in the atmosphere. The model is based on the Monte-Carlo CORSIKA tool, which simulates full development of an electromagnetic-muon-nucleonic cascade in the atmosphere, with the FLUKA package used for low energy interactions. The model is applicable to the entire atmosphere, from the ground up to the stratosphere. A comparis ... More

It has been claimed (Szensmark, 2007, and others) that observed correlations of terrestrial cloud cover with 'the cosmic ray intensity' are casual. The possibility arises, therefore of a connection between cosmic ray intensity and Global Warming. If true, the implications would be very great. An examination of the situation is made.

One of the main questions which is interested to the cosmic rays community is the possible impact of cosmic rays of solar and galactic origin on Earth’s atmosphere and climate. Here we investigated one of the mechanisms that relay (solar and galactic) cosmic rays variability and optical atmospheric changes. This link seems to be of great importance for the overall solar-terrestrial rel ... More

By the solar flare, a large number of solar protons are usually accelerated into high energies. When the intensities of solar protons are very strong, they are observed as a phenomenon, the Ground Level Enhancement (GLE). However, it is used to be reported in the cosmic ray conferences how much percentage they increased in comparison with the flux of the galactic cosmic rays. In order t ... More

Muon diagnostics is a new technique of remote monitoring and forecasting of the development of various dynamic processes in the heliosphere and in the atmosphere and magnetosphere of the Earth based on the analysis of spatial- angular and temporal variations of muon flux simultaneously detected from all directions of upper hemisphere. For practical realization of the technique multi- direc ... More

Measurements of muon flux in the atmosphere have been performed by Lebedev Physical Institute during sea expeditions in November, 1975 - March, 1976 period. This survey covered a wide range of latitudes with geomagnetic cutoff rigidities Rc from 0.8 up to 14.2 GV. The data on muon flux as a function of atmospheric depth ( X~ 10-1000 g/cm2) were obtained. On the other hand based on ... More

The galactic cosmic ray (GCR) intensity often shows a dramatic variation responding to the arrival of interplanetary disturbances at the Earth. Aiming to observe such a variation with muon detectors, we constructed a prototype network of multidirectional detectors in March 2001 by installing a small detector in Brazil in addition to two existing detectors in Japan and Australia. By March ... More

Be-7 is produced by interaction between cosmic rays and nitrogen or oxygen in the atmosphere. The variation of its concentration indicates the variation of cosmic-rays intensity. Cosmic rays which reach the earth are modulated by the solar activities in the heliosphere. It is important to investigate the relationship between the concentrations of Be-7 and the solar activities, because of t ... More
