What is the Product Requirements Editor (PREd)?
The Product Requirements Editor (PREd) is a web application for the configuration and maintenance of real-time dissemination requirements.
The PREd is currently available to the following real-time forecast data users:
ECMWF Member and Co-operating States (ECMWF members)
NMHS licence holders
Maximum charge licence holders (under the old costing system) or users with the silver or gold service package (new service charge model)
Access to PREd is arranged as part of your real-time forecast data delivery set up.
After you have selected the data you require by browsing the ECMWF catalogue of real-time products. Your data is installed in the Product Requirements Editor (PREd), where the requirements are validated according to: 1) what's available and 2) which data you are permitted to access (not all customers pay to access the high-frequency products). Once the data has been installed, files are produced by the product generation system - you can review these files on the ECMWF Production Data Store (ECPDS)

Access the Product Requirements Editor
Log in to the Product Requirements Editor (PREd) web interface, using your username and password.
noteTo access PREd, you need your password. To access ECPDS, you need your token.
Destinations and feeds on the PREd
Requirements are grouped in logical containers. At the top level we have the organisation. Organisation contains 1 or more destinations, each representing a physical host.
Destinations contain feeds. These are containers where you will be able to see the editor and the dissemination requirements.
Installing data on the PREd
If you want to install new data to test, please install your data in a test feed (that starts with T). If you would like to install your requirements in operations right away, you can install them in an operational feed.
You can install your data with the help of so-called snippets (<>), see below for more information about this tool.
By clicking on the bug symbol, you can check if your data configuration validates. The tools below can help you.
If everything is alright, the bug turns green. You can then send in a publication request.
