Sites: Many sites in different regions of Germany
Result:
After a strong, but systematic correction, the reanalysis data show very realistic wind roses, wind speed frequency distributions and diurnal courses of the wind speed in larger heights above the ground at all sites, except for those with complex structure on a small scale.
In 2019, a wind measurement with a Sodar was completed successfully in the high mountains of Bosnia under winterly conditions.

In September 2019, aj develops a methodology to calibrate the wind flow calculation. This allows for adapting the local wind shear and the horizontal variation of the wind resource simultaneously. Thus, comparison turbines of very different placements and hub heights can be incorporated and uncertainties can be reduced significantly.
aj completes successfully a wind measurement with Sodar to assess the wind shear on a site in Marocco. aj completes successfully a wind measurement with Sodar to assess the wind shear on a site in Marocco.
Oldershausen, 15 May 2018: A new study of aj shows that the wind resource of the years around 1990 cannot be considered as very exceptional any more. Consequently, these years must be included in the long term reference period, if the result should be balanced. Download of the report Wind D NAO-Index E 15.05.2018 aj
