Abstract In order to improve the data observation quality of atmospheric particulate matter and shorten the occurrence time of anomaly data regarding the particle concentration,this paper classifies and studies the anomaly data measured by β-ray atmospheric particulate matter monitor.As for the anomaly phenomena of common observation data,such as the concentration of particles exceeding the maximum or minimum permitted value,data “inversion” and irregular variation of data,it also analyzes the corresponding fault causes,providing basis for the summarization of troubleshooting methods.
