KAIRA plasma parameter fit


Ilkka Virtanen and Niklas Siipola have been analysing some of the KAIRA data that was recorded during the previous Finnish EISCAT campaign. The following plots show bi-static incoherent scatter plasma parameter profile plots obtained using KAIRA. The results are in good agreement with the Tromsø measurements, and also show for the first time that a simultaneous bi-static plasma parameter profile can be obtained using a phased array incoherent scatter radar receiver. This is still work in progress, but this is yet another step in the direction of KAIRA performing routine incoherent scatter plasma parameter measurements.

The PI of the experiment was Anita Aikio and the purpose of the experiment was to 1) obtain the first tri-static EISCAT VHF measurements, and 2) to leverage the multi beam capability of KAIRA to obtain a profile of wind velocity vectors (due to the lack of a third station, only two components of the velocity vector can be obtained).
