KEOPS/ESRANGE 15-22 December 2006
Program
- extention of the scientific observations on-board Demeter up to lat of 72°
- mode « burst» for the Demeter instruments IAP (thermal/suprathermal
ions) and ICE (electric field)
- triangulation of the optical cameras in the footprint of Demeter
- simultaneous observations of arcs with the interferential filters of 427.8,
557.7, 630, 844.6 nm of ALIS and large band of ALFA all-sky
- increased spatial/temporal resolution of the radar measurements in the
regions magnetically conjugated with the Demeter orbit
Study
- spatial multi-scale observations inside the auroral arcs :
Demeter : 3 km for plasma temperature, velocity, electric field
46 m for plasma density ;
SuperDARN : 15 km along the beam
ALIS cameras : 300-500 m at zenith;
ALFA all-sky: 200 m at zenith, 7 km at horizon.
- temporal multi-scale observations
30 s of ALFA all-sky
0.1 s of ALFA HRST
- separation of the temporal and spatial variations
- mechanisms of the O+ outgoing in the regions of the parallel currents
Example of the conjugated measurements, 19.12.06
ALFA PLC and HRST simultaneous observations, 20.12.06
