Summary
Enhancements in the amplitude of returns from a Medium Frequency (MF)radar at Davis, Antarctica have been identified and their potential use as a measure of PMSE has been explored. A method for finding these enhancements has been applied to data spanning the period from mid-1995 to the end of 1997. The character of these enhancements on short- and long-time scales has been studied and factors that may affect their detection have been considered. It has been found that they are short lived (2 min or less beingmost common) and largely limited to the months around summer. Apart from describing the character of these amplitude enhancements, this study illustrates the potential pitfalls associated with identifying a proxy measure of PMSE.
