Classification of AQ510

For more than a year, AQ system have collected data from four AQ510 SoDARs and have gathered 24 months of data with concurrent met masts. This large data base lays ground for an intensive analysis on AQ510 sensitivities in regards to environmental parameters to ensure that AQ510 measures accurately in all conditions.

As can be seen in the figures above, AQ System has taken the requirements one step further to reduce uncertainty and better quantify AQ510’s sensitivities in all seasons. Since most wind assessments are over a duration of one year, AQ Systems have decided to use one SoDAR against a met mast for the same period.

The excellent final standard uncertainty given on these heights show a clear trend of increased certainty the higher up it measures. The rationale for the lower heights being more uncertain is partially due to the moderate complexity in the terrain at both sites, which has a larger influence at lower heights.  Using a 180 m met mast for classification allows us to have almost all heights classified (missing 200 m). Which makes AQ510 the only RSD that is classified to those heights and the only classification that has meet all the requirements.

The rationale behind using a 180 m met mast is that the wind industry is building higher and higher wind turbines and will soon need these heights to be part of the classification.

The full document will be available before the end of February. Please contact your AQ personal for a copy.

In the 1960's we were focused on helping pilots to land properly...
