test instructions for NMHS/max charge

Users are reminded that maximum Charge and NMHS licences currently permit you to 12 changes per year to your real-time data requirements (according to your contract).

Changes are approved at ECMWF discretion and we are currently reviewing the limits. 

  1. Access the Product Requirements Editor (PREd) web application, using your username and password.
  2. Select the data you require by browsing the ECMWF catalogue of real-time products. This web catalogue reflects the forecast products available for dissemination.​
  3. If changes are required to your licence (for example, the addition of High-Frequency Products) contact data.services@ecmwf.int
  4. Modify your real-time requirements in the Product Requirements Editor (PREd)
    Requirements are validated according to:​
    1. What's available
    2. ​Which data you are permitted to access (not all customers pay to access the High-Frequency Products).
  5. 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)
