An important milestone in @ECMWF history: all @ECMWF graphical charts freely and openly accessible by everyone thanks to the continuous support of @ECMWF Member and Co-operating States #OpenData #WeatherForecast #extremeweather
From today, all ECMWF graphical products are free and accessible to all! Medium-range, extended-range and long-range forecast charts of temperature, wind, precipitation, clouds and ocean waves are just some of the products available. @CopernicusECMWF @WMO

@stormchaserjs @FPappenberger as mentioned, for a number of reasons, this is not what we generally do. But we are looking at options how to address this issue possibly by using a shorter model climate

@stormchaserjs @FPappenberger we are discussing how to deal better with this issue. Generally speaking ECMWF is not bias correcting its forecast products if this is what you meant with BC

A nice visualisation and interesting use both of @CopernicusECMWF @ECMWF ERA5 data and of free weather API making the data easily accessible!
We know #GlobalWarming is real. But how have temperatures developed in different locations around the globe? I built a web app that creates graphs like this for most places on earth. It shows how daily temperatures compared to a reference period (by default 1961-1990). #dataviz

Actually during the same week the @ECMWF European Weather Cloud was also used to support the Data Assimilation training course This cloud can support not only one virtual classroom but many at same time: a Virtual School!
Another example of using the European Weather Cloud ( at @ECMWF to support training activities. These cloud resources are also available for research projects as part of

This @ECMWF Special Project framework supported important research such as setup of limited area ensemble forecast systems over Europe
Have you got a weather or climate project idea for which you need #ComputingResources? Researchers from any organisation in ECMWF Member States can apply for such resources as part of our Special Project framework. Find out more ➡️

Important paper from @ProfMatsuoka @thoefler et al. captures, in a succinct and readable form, important areas of uncertainty and debate in #HPC. There is surely *some* truth in each myth presented, except for the word ALL in each case. But how much?
