1. European Digital Upper Atmosphere Server DIAS A project co-funded by the eContent programme of the European Commission

2. Overview The project aims at the development of a European digital data collection on the state of the upper atmosphere and on the efficient promotion of this collection to the world market.

3.  To develop a pan-European digital data collection on the state of the upper atmosphere based on historical data collections and on the real-time information provided by several European ionospheric stations.  To develop a new digital server for the management and distribution of this collection, based on cutting edge technologies.  To develop, through the collaboration of the private sector companies that belong to DIAS consortium, all necessary actions for the efficient promotion of this pan-European digital data collection and new added value products based on the raw data, to the European and worldwide market. Objectives

5. Why Europe needs DIAS? Currently, the existing digital European stations operate independently  Currently, the existing digital European stations operate independently  This independent operation creates several barriers for transforming this information into usable data, products and services,failing to address the increased market demands for a unified collection of historical and real time upper-atmosphere data, especially nowcast and forecast services for the European region.  This independent operation creates several barriers for transforming this information into usable data, products and services, failing to address the increased market demands for a unified collection of historical and real time upper-atmosphere data, especially nowcast and forecast services for the European region.  DIAS will overcome this problem by operating a system competitive to those that exist already for Australia and the US.

6. Groups of potential users of DIAS products and services  Aviation industry (civil and military)  Defense  HF communication Systems  Satellite operators  Commercial satellite designers  Navigation Systems  Ground-based systems managers and operators  Upper atmosphere researchers  Seismic hazards researchers

9.  Real-time and archive ionograms  Real-time and archive SAO files  Real-time f-plots of fmin, foF2, and M(3000)F2 Data, products and services

10.  Ionospheric maps over the European area of monthly median foF2 and M(3000)F2 [based on SIRM, Zolesi et al., 1993]  Ionospheric maps over the European area of the real-time foF2 and M(3000)F2 for individual epochs for the now-casting frequency management [based on SIRMUP, Zolesi et al., 2004]  Ionospheric maps over the European area of instantaneous foF2 and M(3000)F2 values at a time specified by the user  Ionospheric forecast maps over the European area representative of foF2 conditions up to 24-hours ahead [based on SIRMUP, Zolesi et al., 2003, calculating the forecasting values according to the Muhtarov et al., 2002 model]. Data, products and services

11. Real-time maps of ionospheric electron density over the European area at user-specified heights [Stanislawska et al., 2001] Maps over the European area of monthly median MUF for different transmission points Real-time maps of the Maximum Usable Frequency (MUF) over the European area for different transmission points.
