Measuring air temperature at the surface of the seawith Datawell buoys

摘要

Though the conditions for measuring the air temperature just above the seawater on a small buoy are notoriously challenging, the concept of compensating for radiation effects and detection of cooling down by evaporation has shown to give accurate and reliable measurements. Land-based validation has shown that the accuracy is better than 0.5°C. The fraction of the time this accuracy of the measurements cannot be guaranteed due to unfavourable conditions at sea is less than 10%. All in all, the CAT4 air temperature sensor has proven to be an effective and valuable instrument to be used in the harsh marine environment and is much appreciated by the Waverider users.
