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 CEMS European Flood Awareness System (EFAS), and the CEMS European Forest Fire Information System (EFFIS).

All data are quality controlled. Data post-processing includes the calculation of minimum, maximum, and mean values as well as the aggregation of totals over different accumulation periods. Data are then provided to CEMS as station lists and grids.

This report provides an overview of the data collection, quality control, and post-processing activities completed during the year 2025.

In 2025, METEO collected real-time data for 11 parameters from 41 data providers and around 26,900 stations. On average, 9,500,000 records were added to the database each day. Furthermore, the database included more than 43,000 stations with historical data.

METEO constantly strives to improve the configuration of the database to enhance product generation. A substantially revised data validation protocol was implemented operationally in 2024 and used for the quality control of near-real time and historic data.

This effort led to an updated version of the European Meteorological Observation high-resolution multi-variable gridded dataset. Finally, this report suggests a future data collection strategy.
