摘　　要：地面气象测温传感器受太阳辐射的影响,测量时其辐射误差可达1 K量级。针对此问题,设计了一种新型地面测温传感器结构。使用计算流体动力学(computational fluid dynamics,CFD)方法将多个气象参数下的仪器辐射误差进行量化,采用粒子群优化支持向量机算法对其结果进行拟合,得到辐射误差修正方程。以076B强制通风仪器的测量值作为温度基准开展场外实验。结果表明,设计的地面气象测温传感器经修正方程修正后的测量结果与温度基准的均方根误差(root mean square error,RMSE)和平均绝对误差(mean absolute error,MAE)分别为0.029 K和0.027 K,可将辐射误差保持在0.05 K以内。To address the problem related to the radiation error that can be up to 1 K caused by the effects of solar radiation on sur-face weather temperature sensors,a novel temperature measuring device was proposed herein.Specifically,a computational fluid dynamics(CFD)method and a particle swarm optimization support vector machine algorithm were employed to quantify the radia-tion error of the device under multiple meteorological parameters,and to fit the results obtaining a radiation error correction equa-tion,respectively.By using the measurement values of a 076B forced ventilation thermometer as reference,a filed experiment was conducted.The results show that,with the temperature reference after correction by the radiation error correction method,the root mean square error(RMSE)and mean absolute error(MAE)of the ground temperature measuring device designed in this paper are 0.029 K and 0.027 K,respectively.The design can keep the radiation error of the ground temperature measuring device within 0.05 K.
