| description | The objective of this paper is to study the effect of different plasma and
dust parameters on Polar Mesospheric Summer Echoes (PMSE) temporal behavior
after turn-on and turn-off of radio wave heating and to use these responses
to diagnose the properties of the dust layer. The threshold radar frequency
and dust parameters for the enhancement or suppression of radar echoes after
radio wave heating turn-on are investigated for measured mesospheric plasma
parameters. The effect of parameters such as the electron temperature
enhancement during heating, dust density, dust charge polarity, ion-neutral
collision frequency, electron density and dust radius on the temporal
evolution of electron irregularities associated with PMSE are investigated.
The possible diagnostic information for various charged dust and background
plasma quantities using the temporal behavior of backscattered radar power in
active experiments is discussed. The computational results are used to make
predictions for PMSE active modification experiments at 7.9, 56, 139, 224 and
930 MHz corresponding to existing radar facilities. Data from a 2009 VHF (224 MHz)
experiment at EISCAT is compared with the computational model to obtain
dust parameters in the PMSE. |
