| Measurement Definition |
Cup revolutions are accumulated every three seconds for the duration of the logging interval. Wind speed is the average speed for the entire logging interval. Gust speed is the highest three-second wind recorded during the logging interval. |
Unit vector components of wind direction are accumulated every three seconds for duration of logging interval. Average direction is calculated from the average of these. |
