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

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

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

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

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

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

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

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
