    • The European Weather Cloud: driving weather applications close to data.

      The European Weather Cloud is the cloud-based collaboration platform for meteorological application development and operations in Europe enabling the digital transformation of the European Meteorological Infrastructure (EMI). The EMI comprises ECMWF, EUMETSAT, and the National Meteorological Services of their Member States.

    • Welcome to the EWC User Workshop 2026

      This course collects all materials from the 9th European Weather Cloud (EWC) User Workshop from the 22nd September 2026, held as a hybrid event at EUMETSAT in Darmstadt during EUMETSAT's 40th anniversary year. Jointly organised by EUMETSAT and ECMWF, the workshop brought the EWC user community together to discuss the latest platform developments, share use cases, and explore where the European Weather Cloud is heading next.

      Here you'll find the presentation slides, session recordings, and supporting material from across the workshop. Whether you joined us on site, followed online, or are catching up afterwards, we hope these resources help you revisit the discussions and learn from the teams behind the EWC and from peers using the platform in meteorology, climate, and environmental science.

      Building the MLCast data ecosystem on the foundations of the EWC

      In this presentation I will outline my experience with using the European Weather Cloud (EWC) to serve as the data hosting service for the MLCast Deep Learining Nowcasting Community (https://mlcast.org), https://github.com/mlcast-community/mlcast-datasets. I will walk through how mlcast-datasets (https://github.com/mlcast-community/mlcast-datasets) was built, how it works and how we make use of EWC to enable the research and development we do on nowcasting using deep learning.

      You have heard it before: in the age of deep learning and big data we need well-defined and accessible datasets (or ARCO, Analysis-Read Cloud Optimised). In this talk I will demonstrate how we achieved this in the MLCast community and show how you can do the same in your situation.

      KAL (Kernel Atmospheric Learner): A Hybrid MSG SEVIRI and Machine Learning Framework for Quantitative Precipitation Estimation in Radar-Absent Regions

      This presentation will introduce the (Kernel Atmospheric Learner), an hybrid machine learning framework, developed and trained on the European Weather Cloud (EWC), for high-resolution daily Quantitative Precipitation Estimation (QPE) in topographically complex regions that lack ground-based weather radar.

      Chris Koliopanos (University of Ioannina)

      12:10 - 12:30

      Visualisation platform for AI Models

      RMI runs a lightweight forecast viewer on EWC that turns AI-LAM weather model output into an interactive map, letting users browse variables and lead times through a simple web interface.
      Forecasts are also made available directly via an S3 bucket for users who want programmatic access to the raw data.
      Together, the viewer and the data bucket show how a relatively simple EWC setup can support both visual exploration and direct data access with minimal overhead.

      Studying the evolution of heat waves in Italy over the present century.

      The study evaluates a suite of climate indicators related to summer heat waves in Italy, aiming to construct a comprehensive, quantitative profile of their evolving characteristics, specifically focusing on frequency, duration and severity over the present century. The base data layer consists of statistically downscaled and bias-corrected projections for Italy, developed by CMCC and Agenzia ItaliaMeteo. The temporal scope of the study is restricted to an extended summer season spanning May to September, capturing the period when heat waves are most acute and pose the greatest risk to human health. Starting from the daily TMAX projections, we calculated the indicators year by year, up to 2100. The reference period, 1985-2014, is used both as the representative distribution to calculate the percentiles and as the time frame to calculate climate normals. Consequentially, we computed the metrics both as absolute values and as anomalies with respect to the 1985-2014 normals. We studied the evolution of those distributions across the chosen periods, in terms of their mean value and standard deviation. Both these two parameters show a projected evolution towards higher values, meaning the occurrence of extreme events from the tail of the distribution are expected to become more frequent. We also studied some specific areas in more detail.
      The study was conducted through a tenancy of the European Weather Cloud dedicated to the Italian initiative for C3S NCP.
