JJG自动气象站气象要素计量性能要求合理性探讨

针对自动气象站的温度、雨量对应的检定规程，就其相关指标和规定的合理性进行探讨。目的在于让检定规程更加完善、合理。根据相应仪器本身的特性，结合实际工作经验，以分析误差构成进行理论推导，得出温度（地温），雨量计量性能要求中最大允许误差等不合理的结果，从误差公式中重新确定了温度、雨量的最大允许误差，分别对规程指标的确定提出了修改建议。

Rationality of Metrological Performance Requirements in JJG Meteorological Elements for Automatic Weather Stations

According to the verification regulation corresponding to temperature and rainfall of automatic meteorological stations, the rationality of the related indicators and rules is discussed. The purpose is to make verification regulation more perfect and reasonable. The error structure is analyzed, and the deduced theoretical formula is given from the characteristics of the instrument itself, combined with the actual work experiences. As a result, it is found that the temperature (ground temperature) and rainfall measuring performance requirements of the maximum permissible error and resolution are unreasonable. The maximum permissible errors of temperature and rainfall are obtained from the error formulas. Some suggestions about the determination of the indicators in the regulation are proposed.
