Barium Release Optical and Radio Rocket (BROR) Experiment
Abstract
The Barium Release Optical and Radio rocket (BROR) experiment aims to study cross-scale energy transfer processes and small- and medium-scale structures in the auroral ionosphere using active modification of the ionosphere by multiple releases of barium and simultaneous optical and radio ground-based observations of the appeared plasma clouds. Combining the data from the rocket experiment with results of the numerical modelling we aim to answer the following science questions: What is the role of small- and medium-scale (few to 10s km) ionospheric disturbances in the magnetosphere-ionosphere interaction? What is the mechanism of cross-scale energy transfer between the auroral ionosphere and thermosphere? How are the plasma waves generated by the ionospheric plasma instability transformed into radio waves? The experiment is planned to carry out at Esrange rocket range, Sweden in September 2022. The scientific novelty of the BROR experiment is simultaneous investigation of the cross-scale energy transfer processes over a wide range of environmental conditions enabled by the release of barium at 4 different altitudes in the range of 120-200 km. Another important advantage of the BROR experiment is an unprecedented support by ground-based instruments and facilities. ALIS_4D will be the main optical facility. ALIS_4D is a multi-station, spectroscopic optical imaging system that allows applying tomography-like methods for reconstruction of the 3D-structure of atmospheric optical phenomena such as aurora and radio induced optical emissions. Optical measurements will be complemented by the all-sky MIRACLE network as well as imagers operated by NIPR, Japan. For the radio measurements we will use the EISCAT radar, the dynasonde and the HF radio receivers. in Kiruna.
