The hourly wind direction from the KNMI weather data table column DD is presented in degrees and oriented towards the north, which means we can use it directly.
| Column | Name | Unit | Dutch Description |
|---|---|---|---|
| 2/B | YYYYMMDD | Date | datum (YYYY=jaar,MM=maand,DD=dag) |
| 3/C | HH | Hour | tijd (HH=uur, UT.12 UT=13 MET, 14 MEZT. Uurvak 05 loopt van 04.00 UT tot 5.00 UT |

Notes
- The values at each hour regard the measurement over the preceding hour up to that time. To obtain the value for 12:00 UTC, the values at 12:00 UTC must be used.
