The CEMS Hydrological Data Collection Centre Annual Report for the reference year 2022 has now been published on the EFAS website, under the section Resources. 

This report provides an overview of the data collection, quality control, and post-processing activities completed during the year 2022.  49 EFAS data providers contributed to the CEMS HDCC database by sharing near real time data from 2,382 stations across Europe, covering 33 countries and 54% of all the European water basins. Starting from 2022, CEMS HDCC is responsible for the collection, quality control, and harmonization of daily historical discharge data for the global domain: 2,588 stations from 98 countries and 46 data providers were included in the CEMS HDCC database. 

The CEMS EFAS team, and particularly CEMS HDCC, would like to thank the EFAS Partners and Data providers that contributed to the CEMS hydrological data collection. Without their collaboration, the delivery of the report and of the service would not be possible.
