Dissemination schedule

Real-time data are pushed to users' servers on a schedule. If you need to re-transmit files you must log in to ECPDS.

Please note that during Summer 2021 we will be moving the schedule shown on this page to our user documentation website. During the transition the table below may fall out-of-date and you must refer instead to https://confluence.ecmwf.int/display/UDOC/Dissemination+schedule
