Abstract Affected by solar radiation,a relatively larger deviation occurs between the value measured by ground temperature observation instrument and the true temperature of free air,reaching 1 ℃ magnitude.Based on this,a ground temperature observation instrument is designed in this paper,which can be used to effectively prevent the solar radiation from irradiating the temperature probe directly and guide the air flow towards the temperature probe.It is verified by experiment that the mean absolute error and root-mean-square error between the results measured by temperature observation instrument developed in this paper and the base value are 0.030 ℃ and 0.035 ℃ respectively,reaching the technical requirement of 0.1 ℃ magnitude.

Key words： ground temperature radiation error temperature observation instrument computational fluid dynamics neural network
