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)

Training Material

A presentation and recording providing an overview of the PREd functionalities, along with guidance on how to begin using the system once access has been granted, are available as part of PREd & ECPDS Training Course Webinars: https://events.ecmwf.int/event/462/

These materials are intended to support users in understanding how to configure and maintain their real-time data requirements within PREd and review generated products via ECPDS.
