On 11 December 2025, the CAMS Global atmospheric composition forecasts were made available through ECMWF Dissemination for a fee.
You can now order and configure the CAMS products through the ECMWF Product Requirements Catalogue and set the delivery to Pre-schedule.
In this way, you can select the data you need and they will be automatically delivered to you as soon as the data are ready.
After placing your order, ECMWF will contact you via our Support Portal to discuss your needs, refine your data requirements if needed, and ensure you receive the most appropriate products.
ECMWF also offers a number of optional services for the delivery of the data, depending on the service package you choose. For details, please see here.
