COST (European Cooperation in the Field of Scientific and Technical Research) is one of the longest-running instruments supporting co-operation among scientists and researchers across Europe and beyond. COST covers basic and pre-competitive research as well as activities of public utility.

COST enables scientists to collaborate in a wide spectrum of activities in research and technology allowing the co-ordination of nationally funded research.

INGV

Ionospheric COST Actions (1991-2009) have gathered a dynamic group of more than 150 scientists coming from a number of countries and their scientific institutions and/or universities..

The International Reference Ionosphere (IRI) is a joint working group of URSI and COSPAR with the main objective to develop and improve a standard model of the ionospheric plasma parameters. Both IRI and all COST ionospheric related Actions have had the similar main research and keep together ionospheric communities for many years.

INGV

Four COST Actions have been carried out since 1991 on Ionospheric Physics and Radio Propagation: 1. COST 238 (PRIME, Prediction and Retrospective Ionospheric Modelling over Europe); 1991-1995. 2. COST 251(Improved Quality of Service in Ionospheric Telecommunication Systems Planning and Operation); 1995-1999. 3. COST 271(EACOS, Effects of the Upper Atmosphere on Terrestrial and Earth-space Communications); 2000-2004. 4. COST 296 (MIERS, Mitigation of Ionospheric Effects on Radio Systems ); 2005-2009.

INGV

The PRIME objectives:

to develop techniques for using ionospheric sounding information taken from existing measuring equipments to generate improved models of the European ionosphere, nedeed to estimate ionospheric propagation effects on telecommunication systems.

INGV

The PRIME principal achievements:

1. Digital data base of routine hourly ionospheric sounding measurements from 27 stations over 4 solar cycles and data base of TEC; 2. Coordinated special vertical and oblique-soundings campaigns; 3. Different methods for long-term mapping, the first time instantaneous ionospheric maps from simultaneous measured data for given epochs, and the development of an ionospheric forecasting capability; 4. A computer program giving: a) monthly median maps for any single epoch; b) diurnal and seasonal trends of the median monthly values at user-specified locations; and c) instantaneous mapped values for a given day and hour based on measured input data.

INGV

COST 251 Action objectives: to demonstrate the practical improvement to terrestrial and Earth-space radio systems of COST 238 (PRIME)-derived ionospheric models, and to further refine these models and to widen their geographical area of applicability between latitudes 35-70°N and longitudes 10° W-60° E and to promote their use;

INGV

Perform studies to influence the technical development and implementation of new communication services, particularly for the GNSS and other advanced Earthspace and satellite-tosatellite applications based on a state-of-the-art documents in the following publication:

COST271 Action achievements:

INGV

COST 296 Action (MIERS) objectives:

• to increase the knowledge required for mitigation of effects imposed by the ionosphere on practical radio systems allowing new and emerging methodologies and techniques to be tested on well characterized samples and to be implement where is appropriate;

• to make applicable results available to the ITU-R and to promote the research aspects to funding agencies such as ESA, ESF, Econtent and FP 6/7 . A good example: DIAS ionospheric maps over the European area for the real-time foF2 specification based on SIRMUP model developed by Zolesi et al. (Radio Science, 39, 2004).

INGV

COST ionospheric actions achievement:

1. NeQuick, a quick-run model for trans-ionospheric applications, 2. COSTprof, a model suited for ionospheric and plasmaspheric satellite-to -ground applications, 3. NeUoG-plas, a model suited for assessment studies involving satellite-tosatellite propagation of radio waves.
