Info

The dissemination schedule shows when each step of a real-time forecast starts transferring to your server. All times on this page are UTC. The delivery windows below span the transfer start of the first and last step, individual steps arrive progressively within the window.

This schedule applies where Pre-Schedule has not been configured. See Pre-Schedule Delivery for earlier delivery options.

Reading the delivery columns: a range such as 05:45 -> 06:12 is a window. On a row with steps 0 to 90 by 1 it means step 0 starts transferring at 05:45 and step 90 at 06:12, with the steps in between going out in order at roughly regular intervals. A single time, such as 12:27, means every step of that ladder starts transferring at the same moment.

Real-time data are pushed to users' servers on the schedule shown. If you need to re-queue files, log in to ECPDS. Note that re-queueing is only available to Member and Co-operating States and to customers on the Silver or Gold package.

Each delivered file is named according to one of our naming conventions (ECMWF, LEGACY or WMO), which encode the model, forecast run and step in the filename. See File naming convention and format for real-time data.
