If you are an ECMWF Member or Co-operating State user, or if you have a silver, or gold service package, you can view your data requirements in the Product Requirements Editor (Product Requirements Editor (PREd)). Basic and bronze users will be able to view their requirements.

Users with an ECMWF Member or Co-operating State status, or those on the silver or gold service packages, can also modify their data requirements directly within PREd. For more information on how to make changes to your requirements, see:
Modifying your data requirements on the PREd

In case you cannot access the application, please contact us by raising a ticket through the Support Portal.

Destinations and feeds on the PREd

Requirements are structured in a hierarchy of logical containers. At the top level is the organisation, which defines the overall scope of configuration. Each organisation contains one or more destinations, where each destination corresponds to a physical host that receives the data. Within each destination are feeds, which act as containers for grouping data requirements. The data requirements themselves are defined within the feeds and determine exactly which data is generated and delivered for each feed.

To make sense of the requirements, it is useful to understand the concept of inheritance. 

Inheritance

• What it does: Displays the data that is being inherited from the preceding dissemination request

• How to use: hover over the  icon

• Future enhancements: selectively paste inherited data into the requirements
