地面气温观测系统设计与实验研究
Design and experimental research of a near-surface temperature observation system
摘要
Abstract
To improve the observation accuracy,a new near-surface temperature observation system and a radiation error correction equation are proposed in this paper.First,a Computational Fluid Dynamics(CFD)method was used to optimize the structure of the temperature measuring system and used to quantify the radiation error.Then,a radiation error correction equation can be obtained by using the BP neural network algorithm.Finally,field observation comparison experiments were performed to verify the accuracy of the new temperature observation system.A 076B forced ventilation temperature observation instrument served as a temperature reference during the experiments.The experimental results show that the Root Mean Square Error(RMSE)and the Mean Absolute Error(MAE)between the measurement values of the new observation system and the reference temperatures are 0.031 ℃ and 0.041℃,respectively.关键词
