 4 June to 6 July 2012   -   ESSL Research and Training Centre  -  Wiener Neustadt, Austria

The ESSL Testbed is a project to enhance severe weather forecasting across Europe. The Testbed provides forecaster training, testing of forecasting tools, and is a platform for interaction for researchers and forecasters.

The ESSL Testbed is organized jointly with the Austrian Central Institute for Meteorology and Geodynamics (ZAMG).

The Testbed is supported by:

In addition, ESSL cooperates with the European Centre for Medium-range Weather Forecasts (ECMWF) and the World Meteorological Organization (WMO) - Region VI.

ESSL Testbed




The ESSL Testbed is a project to study severe weather across Europe through experimental forecast operations.


The Testbed tests new products to support the forecasting process, while providing training and interaction between forecasters and developers.

To participants, both forecasters and developers, the Testbed offers:

·         One week of intense severe weather forecasting training, primarily using real-time weather as it occurs across the European continent.

·         Real-time testing of new forecasting and nowcasting tools that are based on model, satellite, radar or observational data.

·         A platform for interaction between the two groups essential to the warning process: forecasters and developers.


Trainings are performed by ESSL staff and external experts. As a basic resource for the hands-on forecast training, standard meteorological data will be available, complemented with the experimental Testbed products. The basic data includes ECMWF, GFS and local model data, as well as EUMETSAT and radar data.

The philosophy is a physics-based approach like the “ingredients-based method” originally proposed by Doswell et al.. Expert lectures will deal with forecasting techniques and the experimental tools.


The testing of products takes place in three steps. Firstly, experimental forecasts are prepared by participant groups. Secondly, these forecasts are verified against the observed severe weather. Finally, the role of the experimental products in the forecasting process is evaluated. The evaluation takes place in group discussions and is recorded through questionnaires. The collected feedback is condensed in a report provided to the product developers. 

Daily programme

Short-range forecast and nowcast operations or study of past cases

(if no severe weather is imminent on that day in Europe)


End of nowcast operations



You and the Testbed

On our way to organizing the Testbed we need you to express your interest in participating, either as a forecaster or as a developer of a product to be tested.

ESSL is investigating the possibiity of organizing the Testbed in June 2012. The ESSL Testbed can already count on support from EUMETSAT, EUMETCAL and several National Hydro-Meteorological Services and commercial project partners. It is however essential that those interested in participation pre-register as soon as possible.

Planned dates:

4-8 June 2012

Testbed on site and remote service

11-15 June 2012

Testbed on site and remote service

18-22 June 2012

Testbed on site and remote service

25-29 June 2012

If a sufficient number of registrations is received, the ESSL Testbed will take place in the new ESSL Training Centre in Wiener Neustadt, Austria – close to Vienna Airport.

Well-priced hotels in various categories are located nearby.
