Our activity

Main directions

• Earth-ionosphere acoustic channel properties research.

• Acoustic disturbances influence on geophysical fields research.

• Solar-Earth relations research.

• Infrasonic field research.

• Atmospheric infrasound influence on ozone layer research.

Major scientific achievements

• The experimental fact of ionospheric transparency increasing for electromagnetic waves of VLF range after acoustc disturbance was found out.

• The fact of relations of atmospheric infrasound and seismic activity on the local region (at the distance up to 1000 km) was found out.

• The fact of relation of solar activity and atmospheric infrasound was found out.

• The fact of atmospheric infrasound influence on total ozone level was found out.

• Active space-ground experiments for study acoustically disturbed ionosphere were carried out with onboard equipment of "DEMETER".

• Experiments for study of acoustic disturance influence in the atmosphere on passing Global Positioning Systems signals were carried out.

Equipment

For main scientific researches the complex of devices were made. There are devices for making artificial acoustic modification of ionosphere, devices for synchronous measuring of atmospheric infrasound, geoelectrical and geomagnetical fields, devices for optical registration of photons in near-UV. Particularly:

• Acoustic generators;

• Infrasound meters;

• Electromagnetic field meters;

• Electric field meters;

• UV radiation meters.

Long-range scientific researches and developments

• Creation of acoustic complex for the scientific supervisions of atmospheric and ionospheric researches and their relation with the «space weather».

• Comprehensive research of atmospheric infrasound as indicator of unstable processes caused by cosmic and terrestrial sources.

• Creation of measuring devices with modern technologies for study geophysical fields variations.

Directions of collaboration
