Using ECMWF's Forecasts (UEF2018)

ECMWF | Reading | 5-8 June 2018

A forum to discuss the use and performance of ECMWF's forecasts and related products

“Using ECMWF’s Forecasts” is open to all ECMWF forecast users. This year's theme will provide an opportunity for participants to showcase innovative ideas, for example weather applications, forecast products or diagnostics tools. It will also provide a framework where participants can share their experiences with ECMWF data and provide feedback on ECMWF products.

2018 theme: “ECMWF model output applications: the only limit is your imagination"

Weather is part of everybody’s life: we are curious about it, we want to plan our day or we use services (like energy, utilities) that are affected by it. Aviation, agriculture, energy, utilities, retail are some examples of sectors connected directly or indirectly to weather.

Weather data are transformed into relevant information to be used in decision making processes. Examples of this are indices alerting of favourable conditions for flu outbreaks and therefore helping people to make informed decisions regarding their health and well-being. Probabilities of winds being above or below specified thresholds provide means to effectively manage wind farms, and probabilities of occurrence of specified weather scenarios help farmers to minimise damages due to mildew on vineyards. These are just a few of the variety of applications that use weather information.

Let’s take a step further and imagine experiencing a severe weather event in virtual reality where you live. Could this experience help to make better decisions? Let us imagine using infographics to communicate forecast confidence. Would that make possible decision-making at a glance? This is what could be done with today’s ECMWF model outputs in addition to those applications in the water, energy, agriculture and health sectors that have already made use of ECMWF data.

UEF2018 will focus on two thematic areas:

  • Processing of model outputs: this session will be dedicated to model output developments or visualisation with particular focus to innovative ideas that support forecasters when issuing weather warnings. Case studies demonstrating the use of new model output developments are welcomed.

  • Impact Forecasting: this session will look at how weather forecasts are used in sectoral applications like water, energy, agriculture, fire and health. Applications aimed at mitigating the impact of severe weather, at forecasting health risks and at minimising adverse impacts of human activities on the environment (for example maximise the use of green energy, minimise the use of pesticides, effective use of medications to prevent allergic reactions) are examples of topics for this session.


The programme will contain informative talks by participants and ECMWF staff, keynote addresses on specific topics to stimulate discussion and interactive sessions to encourage networking.

This event starts on Tuesday lunchtime and finishes on Friday lunchtime.

The poster session and drinks reception will be on Tuesday 5 June 2018 in the afternoon.

The meeting dinner will be on Wednesday 6 June 2018 in Reading town centre.

#OpenDataHack2018 is taking place on the Saturday and Sunday following the UEF. Note that this is a separate event; if you wish to attend you will need to register on the Hackathon web page.
