Frøya wind data (1Hz).

<p>Herewith we present the extended 1Hz dataset of wind measurements from a Skipheia meteorological station on the island of Fr&oslash;ya on the western coast of Norway, Trondelag.</p> <p>The data binned in 10 min averages can be find at:&nbsp;<a href="https://doi.org/10.5281/zenodo.2557500">https://doi.org/10.5281/zenodo.2557500</a></p> <p>The site represents an exposed coastal wind climate with open sea, land and mixed fetch from various directions. UTM-coordinates of the Met-mast: 8.34251 E and 63.66638 N.

The distance between the masts is 79 m.</p> <p>Data is binned in years and months and stored in a&nbsp;&lsquo;*.txt&rsquo; tab-separated values&nbsp;file.</p> <p>Data column order is described in&nbsp;SkipheiaMast2_header.txt and&nbsp;SkipheiaMast4_header.txt, where WSx is the&nbsp;wind speed (m/s), WDx is the wind direction (360 deg),&nbsp;ATx is the air temperature (deg C) and x designates the instrument number. The instruments are numbered starting from the ground.</p> <p>Example:&nbsp;For Mast2 (6 pairs of anemometers, ground temperature + 6 temperature sensors on the mast) that means that AT0 is the ground temperature. WS1 and WS2 are wind speed records at 10 m level. WS3 and WS4 are wind speed records at 16 m. For Mast4 (2 pairs of anemometers) that means that WS1 and WS2 are wind speed records at 40 m level. WS3 and WS4 are wind speed records at 100 m.</p> <p>Detailed site description with wind climate description can be found in attached analysis: Site analysys.pdf.</p> <p>Additional information and analysis can be found in&nbsp;listed below works, using data from Fr&oslash;ya site:</p> <p>Bardal, L.
