Climatology - 0801-Hundhammer-30m_1year

The wind climatology is presented as a wind rose, giving the average wind speed distribution divided in velocity intervals (bins) and wind directions (sectors). The original wind speed data are divided in 40 bins, whereas in the graphical wind rose presentation all occurrences of wind speeds above 16 m/s have been lumped. Incoming wind directions are divided in 12 sectors, where the first sector is centred around north.
