Uncertainties in Reanalysis Data for Wind Energy

Wind resources show strong variability across space and time — a challenge that climate change further amplifies. Evaluating this variability is key for accurate Energy Yield Assessments (EYA), yet it raises important questions about the reliability of historical datasets and the uncertainties they introduce.

In this recorded webinar, Elies Campmany (Vortex) and Gil Lizcano (Climate Scale) will present an overview of reanalysis datasets fit for purpose in the wind industry and explore methods to examine ERA5 beyond the usual performance metrics. Together, they discuss how to assess intrinsic uncertainties linked to data assimilation quality, time period, and region — and what this means for long-term wind resource assessments.

Watch the session to gain practical guidance on how to use reanalysis data confidently when accounting for multi-decadal wind variability.

WHY WATCH THIS WEBINAR

Wind resource assessments rely on reanalysis datasets such as ERA5 — yet their intrinsic uncertainties are often overlooked.

In a context of multi-decadal variability and climate-driven shifts, understanding the limits and reliability of historical datasets is essential for robust Energy Yield Assessments (EYA).

In this recorder webinar, you will:

  • Gain clarity on how reanalysis datasets are built and what “fit for purpose” truly means for wind energy applications.
  • Learn how to evaluate ERA5 beyond standard performance metrics.
  • Understand how data assimilation quality, regional characteristics and time period influence uncertainty.
  • Discover practical approaches to account for long-term wind variability with greater confidence.
  • Improve the reliability of your energy yield analyses by adding climate change into the equation.

WHAT WE COVER

  • Overview of reanalysis datasets used in the wind industry
  • ERA5 fit for purpose and performance
  • Impact of data assimilation quality on wind assessments
  • Regional and temporal variability considerations
  • Implications of multi-decadal variability for EYA
  • Practical recommendations for improving confidence in long-term wind resource assessments
