探空湿度传感器太阳辐射误差理论修正与实验验证
Theoretical Correction and Experimental Verification on Solar Radiation Error of Sounding Humidity Sensor
摘要
Abstract
In order to correct the influence of solar radiation on sounding humidity measurement,the mechanism of humidity measurement errors caused by solar radiation is first analyzed and studied.Then,the computational fluid dynamics method(CFD)is used for simulation,and hardware circuits and experimental verification platforms are designed and constructed.The simulation results of computational fluid dynamics show that altitude,solar radiation intensity,and solar altitude angle have a positive correlation with the temperature rise of the humidity sensitive resistor.The temperature rise can reach 5℃,resulting in a relative humidity measurement error of 20%.In the experi-mental verification test,it is found that solar radiation cause dry bias errors in humidity measurement,and the larger the temperature rise,the more significant the dry bias errors in humidity measurement.This is consistent with the theoretical calculation results,indicating that CFD theoretical simulation can be applied for correcting solar radiation errors in sounding humidity measurement.关键词
