Outline• AMISR at PFRR.• Auroral imagery information.• Examples of coordinated radar and
optical research.• “Straw man” camera requirements and
design.• Data acquisition needs.• Infra-red imager for high latitude MLTI
research.
AMISR
•Solid state phased array radar.•Rapid pulse to pulse beam steering
capability.•3-D imaging of ionospheric properties.
Two new facilities: •Resolute Bay, Canada.•Poker Flat, Alaska.

AMISR at PFRR
Pointing: 74° elev., Azi. 15° EField of view: ±25° (steerable)Full beam width: 1° (half power)Co-aligned optics: narrow field monochromatic auroral imager and CCD spectrometer.
Complimentary Imaging Capability
•Essential context “big picture” information to aid and complement the interpretation of radar data.
•High-resolution 2-D morphology and dynamics over a broad range of auroral forms.
•Comparative measurements of different auroral emissions (energetics) using broad and narrow filters.
•“Post-hoc” temporal-spatial photometry on selected narrow band auroral emissions.
•Real-time data with “in field” pointing capability to enhance the selection of radar measurement volume.
