Operational performance testing and evaluation of the visual range obstacle phenomenon instrument under low temperature weather conditions
The article utilizes the PM10 and PM2.5 data observed by three different models of visual range obstacle phenomenon instruments installed at the Xilinhot National Comprehensive Meteorological Observation Test Base.Under the basic conditions of data integrity,the reliability and adaptability of each instrument under low temperature weather conditions are analyzed.Data consistency analysis and evaluation are conducted on two devices of the same model to test the application effect of visual range obstacle instruments in low temperature environments.After experimental testing,various models of equipment have high reliability,stable operation,and strong adaptability in low-temperature environments.By conducting absolute deviation analysis on 6 devices of 3 models,it was found that the devices passed consistency evaluation in lowtemperature environments.The research results provide important reference for the operational application of the visual range obstacle phenomenon instrument.
