Due to essential maintenance work on Tuesday 29th August 2023 between 06:00 and 14:00 UTC, there will be no access to CAMS European forecast data for dates more than 4 days old. We are sorry for the inconvenience this may cause.

CAMS European air quality forecasts for the past 4 days will continue to be available from the Atmosphere Data Store (ADS) as usual.

We will update this post when access to the complete CAMS European air quality forecasts will have been restored.

We recommend users to 'Watch" this announcement (click the 'Watch' button at the top right of the page - you will need to login) to receive email notifications of updates made to this page.
