Improved potential wind time series for extreme wind statistics
In 2009, the study "Improving potential wind for extreme wind statistics" by
Wever and Groen was completed. This study was done in close cooperation with
Waterdienst and Deltares. Based on 10-minute data, that are being stored on an
operational basis since 2003, an improvement has been developed in deriving Exposure
Correction Factors (ECF). The study is described in KNMI
Scientific Report WR2009-02, which can be downloaded here.
Additional to the report, potential wind time series used in the study are
available for download from this page.
20090515_update_msr.zip: Hourly values of measured wind speed at sensor
height.
20090515_HYDRA_up.zip: Hourly values of potential wind speed, based on the
original algorithm as used in the HYDRA project (also available here).
20090515_update_up.zip: Hourly values of potential wind speed, based on the
new algorithm for deriving ECFs as described by report WR2009-02.
Note: please check carefully which value of reference roughness
length the data is based on, as this may vary between both algorithms for some stations. This
information can be found in the header of each data file. The data can be
easily translated to other reference roughness lengths, as described in report
WR2009-02.
