我们已经使用非相干散射雷达测量在极地电离层研究离子成分的变化对E和F区电导率和电导的影响。我们发现，这些变化是次要的，在太阳活动极小期的条件下，电子密度超过170公里的霍尔和小于20%的佩德森电导贡献可以忽略不计。这支持了Chatanika和Sondre Stromfjord雷达获得的类似结果，但与理论预测相反。
We have used incoherent scatter radar measurements in the polar ionosphere to study the effects of ion composition variations on the E and F region conductivities and conductances. We find that these variations are of minor importance and that during solar minimum conditions the electron density above ∼170 km contributes negligibly to the Hall and less than 20% to the Pedersen conductance. This supports similar results obtained by the Chatanika and Sondre Stromfjord radars but is in contrast to theoretical predictions.
