英文摘要	Accurate air temperature data is necessary to conducting climate research, carbon tax, and emission reduction estimation. However, the temperature error of temperature data provided by a non-aspirated multi-plate radiation shield is on the order of 1 °C due to various factors, especially solar radiation. To reduce this error, a temperature error correction method based on a method of computational fluid dynamics (CFD) and a method of extreme learning machine (ELM) for a radiation shield is proposed. The CFD method is employed to quantify the temperature errors of this type of shield. Then, the ELM method is adopted to form a universal temperature error correction equation. Finally, field experiments are performed to verify the correction accuracy. A 076B aspirated radiation shield served as a temperature reference. The root mean square error (RMSE) and the mean absolute error (MAE) between the measured temperature error results of a 41003 shield provided by the experiments and the corrected temperature error results from this correction method are 0.06 °C, and 0.056 °C, respectively. The RMSE and MAE of a 5980 shield are 0.074 °C and 0.062 °C, respectively. These results indicated that the temperature data might be expected to achieve the accuracy of 0.1 °C by using this correction method. © 2021 Elsevier B.V.
