User Needs

  • Indices to characterize the state of the ionosphere for radio communication and satellite navigation purposes


Working Team Goals

  • Determine widely used quantities that can be utilized for model-data comparison¬†
  • Obtain scintillation/irregularity data collected at different geographic locations using different instruments
  • Evaluate the capabilities of current models by performing model-data comparison assessment, during different geomagnetic conditions and at different geographic locations.
Challenges:
  • The physics behind the significant longitudinal variability of scintillation/bubbles
  • Role of external and internal drivers, especially to understand the longitudinal scintil lation variabilities
  • Potential drivers for quiet time scintillation/bubbles
  • Uncertainties between observations and models


Working Team Deliverables


Physical Quantities and Metrics for Model Validation

  • S4-index, ROTI, sigma-phi
  • Onset time and duration of scintillations above a certain S4-index level
  • Maximum/peak value of the scintillation index
  • Spatial variability of scintillation activity


Available Data Sources

  • GNSS receivers / S4 index and ROTI
  • UHF/VHF receivers
  • LEO satellite in-situ density


Participating Models
Please contact the team leads for additional model suggestions

  • PBMOD
