for the high-latitude ionosphere under solar minimum conditions
Abstract. Maps of GPS phase scintillation at high lati-tudes have been constructed after the first two years of op-eration of the Canadian High Arctic Ionospheric Network (CHAIN) during the 2008–2009 solar minimum.

| Summary: | Abstract. Maps of GPS phase scintillation at high lati-tudes have been constructed after the first two years of op-eration of the Canadian High Arctic Ionospheric Network (CHAIN) during the 2008–2009 solar minimum. CHAIN consists of ten dual-frequency receivers, configured to mea-sure amplitude and phase scintillation from L1 GPS signals and ionospheric total electron content (TEC) from L1 and L2 GPS signals. Those ionospheric data have been mapped as a function of magnetic local time and geomagnetic lati-tude assuming ionospheric pierce points (IPPs) at 350 km. The mean TEC depletions are identified with the statistical high-latitude and mid-latitude troughs. Phase scintillation occurs predominantly in the nightside auroral oval and the ionospheric footprint of the cusp. The strongest phase scin-tillation is associated with auroral arc brightening and sub- |
