We are pleased to announce that a new dataset have been published on 1st February 2023, in the Atmosphere Data Store (ADS):

[CAMS European air quality forecasts optimised at observation sites](https://ads.atmosphere.copernicus.eu/cdsapp#!/dataset/cams-europe-air-quality-forecasts-optimised-at-observation-sites?tab=overview)

This dataset provides&nbsp;every day, hourly timeseries of air quality forecasts&nbsp;at&nbsp;European&nbsp;observation sites that have been&nbsp;optimised using&nbsp;a Model Ouput Statistic (MOS) method.

The dataset may now be downloaded from the Atmosphere Data Store either interactively using the ADS web interface ("[Download data](https://ads.atmosphere.copernicus.eu/cdsapp/admin#!/dataset/cams-europe-air-quality-forecasts-optimised-at-observation-sites?tab=form)") or programmatically using the&nbsp;[CDS API](https://ads.atmosphere.copernicus.eu/api-how-to)&nbsp;service. Documentation is also available.

For any enquiries regarding this dataset, please&nbsp;[contact us](https://confluence.ecmwf.int/category/cd)&nbsp;(ECMWF login required).
