自愿观测船（VOS）对海洋空气温度（MAT）的观测已知由于传感器环境的太阳加热而存在显著偏差。MAT和湿度观测通常使用安装在史蒂文森屏幕上的湿球和干球温度计或干湿计进行。这些仪器通常安装在桥翼或轮室顶部。如果不仔细放置，则仪器可能暴露在未受干扰的环境条件下，并且通风不足，导致MAT和湿度的观测结果有偏差。
Observations of marine air temperature (MAT) by Voluntary Observing Ships (VOS) are known to contain significant biases due to solar heating of the sensor environment. MAT and humidity observations are usually made using wet‐ and dry‐bulb thermometers housed in Stevenson screens, or with psychrometers. These instruments are typically mounted in the bridge wings or on the wheel‐house top. If not sited carefully then the instruments can be poorly exposed to the undisturbed environmental conditions and have inadequate ventilation, leading to biased observations of both MAT and humidity.
