The workplan for the period 1 July 2005 – 30 June 2006 has been approved by MC as follows:
To maintain the data base of retrospective and real-time measurements based on the near-Earth space plasma monitoring by vertical incidence, oblique sounding networks and GNSS techniques;
-
To study the data ingestion and assimilation into ionospheric models;
-
To study climate of the upper atmosphere including long-term ionospheric trends, gravity and planetary wave effects on propagation and ionospheric space weather;
-
To review the ionospheric effects on advance terrestrial system and identify areas of mitigations;
-
To review scintillation monitoring and modelling over relevant areas with emphasis on scintillation effects, their physical nature and impact on ionospheric radio systems;
The workplan for the period 1 July 2006 – 30 June 2007 has been proposed as follows:
-
Near Earth space plasma modelling and forecasting: Improvement of the methods required for ionospheric short-term forecasting, nowcasting and instantaneous mapping (including 3-D mapping) and their careful testing as well development of models and broadening of the available experimental knowledge for the HF channel evaluation;
-
Topside ionosphere and TEC models: Development towards better agreement with observed TEC, foF2 and bottomside models. Better understanding of wave-like oscillations in the ionosphere towards inclusion of regular/predictable phenomena into ionospheric prediction models;
-
Improved understanding of ionospheric effects on radio systems: communication, direction finding and radar systems;
-
Space Plasma effects: Investigation on the medium and large scale effects during severe ionospheric perturbations and their relationships to space weather. Impact studies of different types of effects on trans-ionospheric radio systems and consequences (e.g. on reliability, availability, accuracy);
-
Mitigation techniques: Studies on mitigation techniques depending on specific needs in different applications;
-
Scintillation monitoring and modelling: Coordinated studies using data from GPS stations at low, middle and high latitudes, comparison of the measurement results provided by different kinds of receivers and statistical analysis; correlation with space weather effects and other driving forces.
