Sensor
| | Wind Speed/Gust | Wind Direction |
| Measurement Range | 0 to 76 m/sec (0 to 170 mph) | 0 to 355 degrees |
| Accuracy | ±1.1 m/sec (±2 mph) or ±5% of reading,
whichever is greater | ±7 degrees |
| Resolution | 0.5 m/sec (1.1 mph) | 1.4 degrees (0 to 355 degrees) |
| Starting Threshold | ≤1 m/sec (2.2 mph) | 1 m/sec (2.2 mph) |
| Turning Radius | 108 mm (4.25 in.) | Approximately 135 mm (5.25 in.) |
| Measurement Definition | Cup revolutions are accumulated every three seconds for the
duration of the logging interval
Wind speed: Average speed for the entire logging interval
Gust speed: The highest three-second wind recorded during the logging interval | Unit vector averaging used; vector components for each wind measurement are calculated every three seconds for duration of logging interval |
