SWWT Ionospheric Effects Topical Group

1. SWWT Ionospheric Effects Topical Group • Agenda • The Low-latitude Ionospheric Sensor Network (LISN): The First Distributed Observatory in South AmericaPatricia Doherty, Boston College • Ionospheric mid and large scale perturbation characteristicsN. Jakowski, C. Mayer, C. Borries, German Aerospace Center • ESA's priorities for ionospheric researchBetram Arbesser-Rastburg, ESA • Ionospheric scintillation monitoring and modellingY. Béniguel, IEEA

2. Wrap up • ESA's priorities • Ionospheric characteristics affecting ESA missions (P-, C- and L-band) • Long-term collection of ionospheric data, improved modelling of distribution of electron density, improved statistics of ionospheric conditions, linking of ionospheric conditions to system performance • Ionospheric perturbations monitoring • Customer oriented approach at DLT (SWACI service) • Many products (perturbations, propagation of disturbances, TIDs,…) • Scintillation monitoring and modelling • In the framework of COST 296 action • Observations from high lat. to equatorial regions • Scintillation data, statistics, models => large share accessible via web portals

3. The Low Latitude Ionospheric Sensor Network (LISN) http://jro.igp.gob.pe/lisn • To address key questions about the physics of the equatorial ionosphere • Develop nowcast/forecasts capabilities on the onset of Spread F ● Installed ● Planned • 70 GPS Receivers • TEC, TIDs • Scintillation • 5 Ionosondes • Virtual height • Bottomside density profiles • Meridional winds • Nighttime capability • 5 Magnetometers • Monitor ionospheric currents • Measure Vertical plasma drifts Jicamarca
