• High-latitude radars: Sondrestrom ISR, Resolute Bay ISR (RISR), EISCAT – data available later; PFISR
PFISR
• Strong wave activity – Jan 4, 2013• Courtesy Mike Nicolls
Millstone Hill ISR
• Main coverage periods:– Jan 4-6, 2013 – wave 1, vortex-shift;– Jan 10-15 – wave 2, vortex split– Other data – Jan 17-18, Jan 24 – Van Allen coverage

Operations on Jan 8-22, 2013; ongoing experiment since Jan 22Nighttime gaps on Jan 13-16 (? – need to verify) for astronomy experiments
• Good quality, nightly data (clear skies)• Red line – wind and temperature data• Green line available• John Noto’s group is working on the
analysis
Arecibo and Millstone Hill FPIs
Jicamarca vertical drift
• JULIA data Jan 1-14, 2013• Periods with both suppressed and enhanced vertical drift
