The Copernicus Emergency Management Service (CEMS) Meteorological Data Collection Centre (METEO) collects, quality-controls and post-processes in situ and ground-based remote sensed meteorological data to provide input data tailored to the needs of the CEMS EFAS (European Flood Awareness System), EFFIS (European Forest Fire Information System) and EDO (European Drought Observatory). By the end of 2020, real-time data delivered by 24 providers for 11 parameters from more than 22.000 stations are collected. On average, 5.500.000 records are being added to the data base each day. Additionally, the data base comprises more than 40.000 stations with historic data.

This report contains an analysis of the meteorological data received by the CEMS Meteorological Data Collection Centre (METEO) for the year 2020 in terms of:

• data providers and provision
• database
• post-processing
• improvements to data flow and post-processing
• gap analysis.

The EFAS team, and particularly METEO, would like to thank the EFAS Partners and Data Providers that contributed to the CEMS meteorological data collection. We would like to acknowledge their dedication to the EFAS project, their commitment and the sharing of their hydrological data. We thank them for their cooperation with METEO, both in the provision of data and for their proactive role in responding to the questions and solving issues. Without their collaboration, the delivery of this report would not be possible.
