Effects of TLEs, TGFs, and LEPs on the Atmosphere
| Questions to be addressed | On-board instruments | Studies to be performed |
|---|---|---|
| ▪ Identify and characterize the respective effects of lightning, TLEs, TGFs and precipitated electrons on: - NOx ,O3 concentrations, - atmospheric waves, - variation in ionization rate, - global electric circuit.
| ▪ Cameras and photometers; ▪ X- and gamma-rays; ▪ Relativistic and energetic electrons; ▪ Wave field measurements from DC to 30 MHz; ▪ Zero+ whistler detector; ▪ Ion probe.
| ▪ Comparison of TARANIS data (TLEs, TGFs, electrons, ion density fluctuations) with atmospheric data (NOx and O3 concentrations, variations in the ionization rate, infrasound, gravity waves, etc) recorded by instruments: - at ground (GPS stations, optical instruments, radars, VLF antennas, infrasound sensors), - on balloon and plane (gamma and X rays sensors, NOx and O3 detectors), - on other satellites (NOx and O3 detectors), and comparisons with other space experiments dedicated to the physics of TLEs and TGFs (e.g. ASIM on ISS). |
| ▪ Model respective effects of lightning, TLEs, TGFs and precipitated electrons on the Atmosphere. | ▪ Development of atmospheric models allowing to understand and then to model the effects. |
