GEO-NET offers the GN-WRF_ML-Spek time series throughout Germany - high-resolution site-specific wind time series with 10-minute temporal resolution.

These time series are used in particular to determine extreme winds as part of stability analyses. They also offer a wide range of possible applications.

What makes our time series special

Our 10-minute time series are calculated using the established WRF model (Weather Research and Forecasting) - one of the world's leading weather models in the wind energy industry. A multi-stage optimization process then ensures impressive data quality:

• Systematic corrections depending on location and height
• Adjustments for diurnal and seasonal variations
• Spectral correction for realistic representation of high-frequency fluctuations

This process combines machine learning with spectral-statistical methods.

Validation

The generated time series were comprehensively validated by GEO-NET. Wind speeds and wind directions at heights of 100 m and 150 m were compared with at least one year of measurement data from up to 37 locations. The results confirm the high quality of the time series:

We would be happy to create a specific time series for your desired location.

• Yield estimation without measurements:  Basis for time series–based energy yield calculations in the absence of site measurement.
• Structural safety verification:  Data basis for extreme wind assessment based on 10-minute time series.
• Long-term correction: Data source for the long-term correction of reference data.
• Hybrid power plants: Combined analysis of wind and PV generation to optimize power production.
• Grid and self-consumption optimization: Comparison of load profiles and production to calculate degrees of autonomy.
