Global pattern
of the ionospheric effects of the large-scale internal gravity waves
caused by auroral activity
Abstract
The
proposed project is aimed at building the global pattern of the
ionospheric effects of the large-scale internal gravity waves (IGW)
caused by auroral activity. The combination of data from the ground
based station network (1957-2003), topside sounder (Intercosmos-19,
1979-82), from in-situ measurements at 350-550 km heights (Cosmos-900,
1977-79) as well as from HF radar observations (SuperDARN and EISCAT,
1994-2004) will be used. This combined database provides a detailed
study of TID effects on a global scale. The method of TID determination
from topside sounding data developed at the University of Sussex will be
tested on these data from Russian and European experiments. IGW effects
were actively studied in IZMIRAN. In particular, an empirical model of
the large-scale IGW effects in the night ionosphere was built (Deminova et al., 1998). This
model was based on the ground based sounding data. Interestingly, during
the analysis of the large volumes of Intercosmos-19 and Cosmos-900 data
many new IGW effects in the topside ionosphere were observed. These
effects still remain by large untouched by the researchers. However,
these detected effects together with the ground based observation
results allow reconstruction of the global picture of the IGW effects
in both day- and night-time topside ionosphere during strong
magnetospheric disturbances (substorms and storms). In order to build
this global pattern the team proposing to investigate several
little-studied before aspects, which are specified below.
