Characteristics of the EIS products
| No. | Product | Output format | Update rate | Spatial Coverage | Data Input | Quality Indicator |
|---|---|---|---|---|---|---|
| EIS1 | Long term predictions of foF2 in the form of maps over the whole European region | ASCII and PNG | Monthly | Europe: Regional Longitude: −10° W – 40° E | Predicted R12 | Not applicable for operational availability |
| Latitude: 34° N – 80° N | ||||||
| EIS2 | Nowcasting regional maps showing the variation of the foF2 critical frequency over the whole European Region. | ASCII and PNG | Hourly | Europe: Regional Longitude: −10° W – 40° E | Real time foF2 autoscaled values from DIAS network | Number and distribution of stations contributing data for the generation of the maps. |
| Latitude: 34° N – 80° N | Relative deviation of the nowcasts from observed values over DIAS stations. | |||||
| EIS3 | Maps of the forecasted foF2 parameter over Europe for the next 24 h. | ASCII and PNG | Hourly | Europe: Regional Longitude: −10° W – 40° E | IMF-B and IMF-Bz real time observations at L1 point from ACE | Relative deviation of the mapped foF2 values from the foF2 forecasted values over each station (forecasted values over each station location are provided in EIS7). This quality indicator refers to the mapping procedure and not to the forecasted routine, which is evaluated in EIS7. |
| Latitude: 34° N – 80° N | Real-time and recent past values of the foF2 form DIAS network | |||||
| EIS4 | Near real-time TEC maps for the European region. | ASCII and PNG | 15 min | Europe: Regional |
|
Number and distribution of stations contributing data for the generation of the maps.The TEC maps are characterised by a quality index which is a measure of the deviation between the model and the GNSS-derived TEC parameters. The smallest the quality index is, the best is the fit between the model-derived maps and the GNSS-derived TEC maps. |
| EIS5 | Alerts for the forthcoming ionospheric disturbances in the European sector. | ASCII | Whenever an event occurs | Europe: Regional | IMF-B and IMF-Bz real time observations at L1 point from ACE | Not applicable for operational availability. |
| EIS6 | Maps of current ionospheric conditions at each station location. | ASCII PNG | 15 min | Europe: Local | Real time and past (30 days) foF2 values from DIAS network of stations | foF2 observed values |
| foF2 running median values | ||||||
| Number of days in the estimation of median | ||||||
| EIS7 | Forecasted foF2 values for the next 24 h over each station. | ASCII and PNG | Hourly | Europe: Local/Single stations | IMF-B and IMF-Bz real time observations at L1 point from ACE | Mean Relative Error and Running Median are available at the main nodes of the network. |
| Real-time and recent past values of the foF2 form DIAS network |
