European Digital Upper Atmosphere Server

1

• European Digital Upper Atmosphere Server
• DIAS
• A European service for the specification and the
  prediction of the state of the ionosphere, funded
  by the eContent programme of the European
  Commission

2
Objectives

• 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 all necessary actions for the
  efficient promotion of this pan-European digital
  data collection and new added value products, to
  the European and worldwide market.

DIAS users requirements survey

• Based on a) web-questionnaire http//www.iono.noa.
  gr/DIAS
• b) meetings with users and experts
• The most highly requested product seems to be the
  real time and historical ionograms, for both
  research and operational purposes (preferable
  time resolution on demand and hourly).
• The users express also significant interest for
  ionospheric specification mainly presented by MUF
  maps and less by maps of electron density
  (preferable time resolution on demand and
  daily).
• Interest was revealed for products concerning the
  forecasting of ionospheric parameters, preferably
  more than one hour ahead.
• Special interest was expressed by the majority of
  the users in receiving ? warnings and alerts ?
  regional maps

DIAS products and services

• Ionograms (from the 8 DIAS stations in a common
  layout)
• Ionospheric scaled parameters (foF2, fmin,
  M(3000)F2, in ASCII and daily plots)
• Daily plot of the Effective Sunspot Number
• Electron Density Ne(h) profiles over each DIAS
  station
• Long term ionospheric predictions (maps of foF2,
  M(3000)F2 and MUF over Europe)
• Ionospheric specification in real-time (maps of
  foF2, M(3000)F2, MUF and Electron Density Ne(h)
  over Europe)
• Short-term ionospheric forecasting (over periods
  from hours to a few days over certain locations
  and maps of foF2 over Europe)
• Ionospheric Alert Indices

DIAS further actions

• DIAS prototype is under evaluation from the
  users
• DIAS final service will be delivered to the
  European Commission in February 2006
• A business plan for the viability of the service
  after the end of the phase sponsored by EC is
  under development
• Several dedicated users meetings for awareness
  and dissemination purposes have already organized
• Next meeting with potential DIAS users will be
  held tomorrow (15 November 2005) from 1530 to
  1630, where we will present the DIAS products
  and services and we will demonstrate the
  functionality of DIAS

DIAS evaluation and prospective

• DIAS overcomes the problem of the independent
  operation of European ionospheric stations,
  unifying the existing data collections and
  providing nowcast and forecast services for the
  European region.
• DIAS basic products and services and their time
  resolution cover satisfactory most of the users
  requirements. Fine tuning adjustments to the
  users requirements could be made.
• Special requests could be the subject of future
  considerations or collaborations (i.e. maps of
  the ionospheric parameters for different regions
  all over the world).
• DIAS could primarily serve the needs of SWENET
  for accurate ionospheric specification and
  prediction information over Europe.
• DIAS has accepted invitations for collaborations
  with organizations from outside Europe
  (Australia, USA) and has to envisage this
  perspective.
