On 1 July, thunderstorms delayed Mexico's FIFA World Cup 2026 match against Ecuador. 6 hours earlier, the ESA-JAXA EarthCARE satellite had observed the storms as they developed — and those observations were assimilated into ECMWF forecasts in near real time. ➡️ earth.esa.int/eogateway/ga...
The Forecasting Global Water Storage Challenge launches today! Participants are tasked with developing an accurate model for short-term prediction of Total Water Storage (TWS) at a global scale. They can take part as an individual or in a team of up to 4 people. ➡️ zindi.africa/competitions...
ECMWF provides a variety of products based on heat and cold stress indices. Thermal stress indices estimate the interaction between the outdoor environment – air temperature, humidity, wind speed and radiation – and the human body. Find out more ➡️ www.ecmwf.int/en/about/med...
The new Children’s Climate Risk Report (2026) by @unicef.org has used ERA5 climate reanalysis data from @copernicusecmwf.bsky.social to build the most detailed global picture to date of climate hazards affecting children worldwide. Read more ➡️ www.ecmwf.int/en/about/med...
Working closely with its Member and Co-operating States, ECMWF continually monitors the performance of its operational forecasts and publishes a wide range of verification information. This is what makes ECMWF forecasts and products trustworthy. ➡️ www.ecmwf.int/en/about/med...
