Abstract In the application process of QX/T 291-2015 Field-calibration Method for Data Logger of Automatic Weather Station,the standard signal generator and data collector are greatly affected by environmental temperature,which can easily lead to data errors,long calibration time,and affect the whole point observation of the station.In response to these issues,suggestions are proposed to expand the detection temperature range,increase the uncertainty introduced by temperature drift in the output of the standard signal simulator,and adjust the stability duration and reading time interval of each calibration point.The research results provide reference for improving the applicability,accuracy,and comprehensiveness of QX/T 291-2015 Field-calibration method for data logger of automatic weather station.
