14. R-ESC Products Variety of products:
Access to existing tools
Datasets and interpretation: levels, comparison with standard models, alerts, …
Utilize models to provide nowcast/forecasts
Development of statistical models
R-ESC development needs and gaps are identified in various ways: interactions with SWE network, user test campaigns, thematic workshops, asset reviews, network review, …
Most gaps are in real-time data, nowcasts and forecasts of environment and their effects.
The focus of R-ESC product development should be on R2O.
Standard APIs and data formats are needed to improve the network.
Improved presentation towards the end user needed.

15. Other R-ESC activities
Mission operations plans and procedures
Defining key performance indicators (KPIs) including measures to monitor the evolution of the SWE network
Setting up product provision monitoring
User test campaigns
Common guidelines for validation
Provide recommendations for standard interfaces, data formats, system design
Requirements tracing throughout the network
Provide input to SWE portal pages …

16. Conclusions
ESA SSA is developing a space weather system to provide services tailored to the end users
Approach based on federated services and assets in SSA Participating States
A variety of products have been included and developed as part of the R-ESC
We welcome suggestions for future developments within the R-ESC domain
