The three-year ECMWF-coordinated project for a prototype system for a Copernicus CO2 service (CoCO2) to monitor anthropogenic CO2 emissions worldwide has concluded its ambitious programme successfully.

ECMWF now provides a much larger open dataset to the public, representing weather forecasts at a higher resolution and a reduction in some release times, after a first set of data was made available in early 2022.

An upgrade of the Integrated Forecasting System to Cycle 49r1, continued progress on machine-learning forecasts, and work with our Member States on a new Strategy will take place in 2024, ECMWF Director-General Florence Rabier says.

Weather forecasting is experiencing a fundamental shift by adding artificial-intelligence-based models to traditional physics-based models. Mariana Clare is one of the scientists helping ECMWF to make the most of what AI has to offer.

ECMWF will hold the fifth international workshop on waves and wave-coupled processes from 10 to 12 April 2024 in Reading (UK) after previous events were held in Melbourne (Australia), Qingdao (China), Guangzhou (China), and Uppsala (Sweden).

ECMWF has started to use Mode-S aircraft observations again to improve the quality of forecasts after this type of data was found to be used in too large numbers during the recovery from the COVID-19 pandemic.

The winter 2023/24 issue of the ECMWF Newsletter is now available. As well as news about ECMWF staff and events, it features articles about new developments and the use that can be made of ECMWF products.

High temperatures from June onwards led to 2023 becoming the warmest year on record by a large margin, close to 1.5°C above the pre-industrial level, according to the EU's Copernicus Climate Change Service (C3S) implemented by ECMWF.

ECMWF’s Member States have approved two major initiatives to intensify the development, testing and implementation of machine learning across their weather forecasting chains.
