2010 a new SuperDARN radar began operation at McMurdo Station, Antarctica.
The radar is the highest latitude radar of the SuperDARN network, both
geographically and magnetically, and the observations have a different
character than those of the auroral zone radars. One particular feature
of note is the high incidence of observed backscatter. When ionospheric
altitudes are above the solar shadow height, the incidence of observation
is greater than 80% for a large portion of the radar field of view. This
is indicative of the near constant presence of field-aligned density
irregularities in the polar cap. This Journal Club presents first observations
and some brief analysis of their implications..
