5-Minute Wind Speed and Direction Dataset Ullstinden

This dataset contains preprocessed wind observations from four stations at Ullstinden, Norway. Files wind_speed_5min_analysis_ready.csv - 5-minute mean wind speed [m/s] wind_direction_5min_analysis_ready.csv - corresponding wind direction [degrees] Both files contain the same 13,262 timestamps and stations. Preprocessing Data from all stations were aligned to a common 5-minute time grid. For the station originally sampled at 1-minute resolution (Valley), wind speed was averaged over 5-minute intervals, and wind direction was calculated using the circular mean. Only timestamps with data available at all four stations were retained. Wind speed observations were restricted to 0.1–30 m/s. The final speed and direction datasets were aligned so that they contain identical timestamps. Wind directions are expressed in degrees from 0° to <360°. Notes Missing or invalid observations are not included in the final dataset. Timestamps are given in Norwegian local time (CET, UTC+1).
