Predicted and observed characteristics of small-scale field-aligned irregularities generated in the F-region by low power HF heating
Simultaneous HF scattering from the different regions of the heated volume is used to investigate characteristics of the small-scale field-aligned irregularities in the F-region. Time of growth, decay rate and saturation level for different pump powers are deduced from the observations and a...

| Summary: | Simultaneous HF
scattering from the different regions of the heated volume is used to
investigate characteristics of the small-scale field-aligned irregularities in
the F-region. Time of growth, decay rate and saturation level for different
pump powers are deduced from the observations and are compared with their
behaviour predicted by the thermal parametric instability model. As a result,
the estimates of the density and of the temperature modifications inside of the
irregularities are obtained.<br><br><b>Key words. </b>Ionosphere (ionospheric
