Ionograms Current digisonde formats: RSF, SBF

Ready, need to change aesthetics (?)

Older digisonde format (MMM): under development

Dynasonde format: under development

Maps of foF2 and M(3000)F2

Nowcasts Runs every 15 min with a granularity of 15 mins

Long-term forecasts Runs every hour - 3 months ahead

Short-term forecasts (foF2 only) Runs every hour - 24 hours ahead

DIAS Meeting, Kiruna 12-15 Sept, 2005

Electron Density Maps Runs every hour Predefined heights of 50 km up to foF2

height, with a step of 50 km

Plots of electron density vs. height over a station

Prototype functionality Solved some internal bugs in DIAS backbone

server Added new products & services in the DIAS

server (rudie.di.uoa.gr/dias) Not many advancements in the interface after

June

Need a tight coordination
