Blog from May, 2023

You will be aware that ECMWF will implement its new cycle 48r1 on 27th June 2023. This cycle upgrade brings significant changes, notably higher spatial resolution for ensemble (ENS) and daily 100 ensemble perturbed runs (ENS-EXT). At the same time, for GRIB 2 encoded parameters, a compression method called CCSDS will be introduced. Therefore, if you haven't tried the 48r1 test data, we urge you to take immediate action so that your production system will be transitioned to the new data smoothly.

You will find more details at the following page: https://confluence.ecmwf.int/display/FCST/Implementation+of+IFS+Cycle+48r1.

To start accessing test data: 

  • For users who have access to the test Product Requirements Editor (TPREd) for the configuration of 48r1 data, the application is available at this link and is connected to the test ECPDS system (XDISS):  https://products.ecmwf.int/esuite/requirements
  • For users who do not have access to the test Product Requirements Editor (TPREd) for the configuration of 48r1 data, you can request access to 48R1 test data at our support portal https://support.ecmwf.int

ECMWF will run also run a webinar on 1st June 2023 (13:00 UTC/14:00 BST/15:00 CEST).  The webinar will focus on the data side: how to access the test data, important changes, and handling CCSDS compression. Please check here for the registration link for the webinar: https://confluence.ecmwf.int/display/FCST/Implementation+of+IFS+Cycle+48r1 .

We thank you for your patience during this complex cycle upgrade.

From 01 July 2023, the EPU unit cost of ECMWF data will be reduced from 0.50 EUR to 0.25 EUR (50% reduction). 

At the same time, the maximum Information Cost will be reduced from 100,000 EUR to 70,000 EUR (30% reduction). 

The maximum Information Cost including high-frequency products will be reduced from 108,000 EUR to 78,000 EUR. 

This price will be applied to all new and renewing licences from 01 July 2023. Existing real-time licensees will be able to give a three-month notice to terminate their existing licences.

From 01 July 2023, our shopping cart will show the cost of data with the new EPU unit price of 0.25 EUR. We are aiming to provide a test version of the Product Requirement Catalogue (PRC) in early June which will allow users to review the impact of the changes.
