Abstract:
The report contains a description of main results obtained within the research
contract between IRE RAS and GFZ Potsdam and results of investigation during period
November-December 2007 – the third stage of the contract. The objectives of
investigation included (1) elaboration and verification of an innovative phase
acceleration-refraction attenuation technique to locate layered and wave structures in
the ionosphere and atmosphere; (2) elaborating of a new technique for identification of
wave origin of temperature and density fluctuations and determination of the intrinsic
frequency of internal gravity waves in the Earth's stratosphere from radio occultation
(RO) data; presentation of a technique for evaluating the vertical profiles of the phase,
amplitude, horizontal wind perturbations, intrinsic phase speed, kinetic and potential
energy of atmospheric waves; (3) maps of waves parameters in the ionosphere and
atmosphere showing their regional, seasonal and diurnal variations with aim to
establish connections with solar and meteorological activity.
