ESSL Testbed 2023


26 – 30 June 2023
Expert week: 3 – 7 July 2023

ESSL Research and Training Centre
Wiener Neustadt, Austria

Please note that ESSL and EUMETSAT also organize joint Testbeds on Severe Convective Storms in preparation for Meteosat Third Generation data. Candidates can apply for acceptance and sponsorship to these testbeds via the EUMETSAT training website.

What is new in 2023?

At this Testbed edition, a number of products will be evaluated, including these:

  • VIIRS satellite data, serving as a proxy for Meteosat Third Generation FCI data
  • A number of improved Nowcasting products from DWD’s SINFONY project
  • ECMWF’s Extreme Forecast Index for CAPE and CAPESHEAR
  • C-LAEF ensemble prediction system from ZAMG
  • other products

For whom is the Testbed?

The goal of the Testbed is twofold. First, it caters for forecasters who want to learn how to forecast severe convective storms using state-of-the-art forecasting tools. Second, it is a hands-on evaluation of new, sometimes experimental, forecast products. This means that both forecasters and developers of forecast products have an interest in the Testbed. In addition, other people having a background in meteorology are most welcome to participate as well. Are you still unsure if the Testbed is the right activity for you? Try our Quiz!
