The long-term reference wind data has now been extended to near-global coverage, and this means that the Spectral Correction method for extreme wind calculation now can be applied nearly everywhere in the world.
For the Spectral Correction (SC) method, there is no need for the WAsP Engineering user to provide any long-term wind data to calculate extreme winds. Instead, WAsP Engineering uses:
- Short-term (around one year) on-site wind measurements provided by the user, and
- CFDDA long-term reference wind data, which is made available by DTU Wind on a computer server in the cloud.
The SC method is implemented in WAsP Engineering 4 and has been tested and validated by DTU Wind.
We implemented the near-global coverage by creating a new server to serve the new dataset, and the update happens when the WAsP Engineering user has downloaded and installed the new version, and then launches a SC method calculation.
For more details, please refer to the following two articles published in the Journal of Wind Engineering & Industrial Aerodynamic:

WAsP Engineering
WAsP Engineering is the industry-standard PC software for calculation of wind conditions, which are relevant for fatigue loads, extreme loads and siting of wind turbines and wind farms. WAsP Engineering is used for sites located in all kinds of terrain all over the world and includes models and tools for every step in the process from wind data analysis to calculation of the wind conditions for a wind farm. More than 1750 WAsP Engineering licenses have been sold in about 50 countries.
Typical WAsP Engineering applications:
- Calculation of wind conditions for IEC site assessment, e.g. wind shear, ambient turbulence, extreme wind and wind flow inclination for individual wind turbines in a wind farm (complete assessment also requires WAsP)
- Siting of wind turbines in a wind farm
