INTRODUCTION Diego Barros — April/2017 plasma bubles observed by tec map 3

Introduction What are plasma bubbles? Plasma Bubbles are equatorial plasma irregularities; Are characterized to be a depletion of the ionospheric plasma density along the magnetic field lines; It has serious implication in trans-ionospheric communications and navigation systems.

INSTRUMENTATION AND METODOLOGY Diego Barros — April/2017 plasma bubles observed by tec map 8

Instrumentation and Metodology Measurement limitations Most of the techniques mentioned above are not able to monitor plasma bubbles continuously in a sufficiently large two dimensional area. All-sky imager - Depend on favorable weather conditions; VHF radar and ionosonde - Cannot cover a wide range; Rocket and Satellite - Only in situ measeruments; Rocket - Sporadic launching.
