多种气象传感器在东南极沿岸观测的对比分析
Comparison of measurements from multiple meteorological sensors along the East Antarctic coastline
摘要
Abstract
Using the data collected by the automatic weather stations along coastal East Antarctica in 2023,this study compares the performance of DHC2(domestic)and HMP155A(imported)temperature and humidity sensors,as well as that of ZQZ-TSF(domestic)and Young 05106(imported)wind sensors.The results show that:(1)the observations from both types of temperature and humidity sensors are highly approximate.The systematic deviation between the sensors is-0.15℃and the major of the gross errors occurs in the range of-25 to-10℃.Systematic deviation for relative humidity(RH)is 0.45%,it decreases with the increase of RH at RH<80%,and increases with RH at RH>80%.(2)The observations from both types of wind sensors are essentially consistent.Systematic deviation for wind speed is as low as 0.02 m·s-1,the major of the most gross errors occurs at wind speeds of 6～7 levels.As wind speed increases,measurements from the different sensors tend to converge and the number of gross errors reduces significantly.For wind direction,the sys-tematic deviation is approximately-3.05°,consistency between the different sensors is high along the pri-mary(east-southeast)and secondary(southeast)wind direction.At low wind speeds,the number of gross errors in wind direction increases,the number of gross errors in air temperature and RH also increase be-cause of insufficient air mixing.关键词
