17-21 November 2008ESWW5 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

17-21 November 2008ESWW5 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

17-21 November 2008ESWW5 3

The Low Latitude Ionospheric Sensor Network (LISN)

•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

•To address key questions about the physics of the equatorial ionosphere

•Develop nowcast/forecasts capabilities on the onset of Spread F
