宝坻双套自动气象站数据对比分析及评估

Data comparative analysis and evaluation of double automatic weather station in Baodi

文章对宝坻双套自动气象站2015年1～6月逐小时气温、相对湿度、气压等观测数据进行了对比分析和评估，阐述了双套站运行的优势，双套站的运行能够有效的保证数据的完整性、降低缺测率。在对数据一致率、粗差率和超差率的分析中发现，气温、相对湿度、气压的观测数据的一致率较高，粗差率和超差率较低，2min平均风速和0cm地温的观测数据差异性较大，粗差率和超差率较高。通过对两套站观测数据差值滑动平均的变化特征分析，能够及时发现数据的异常变化，可得到更为准确可靠的观测数据。

The hourly data of temperature, relative humidity, pressure in Baodi double automatic weather station from January to June 2015 were compared and evaluated in this paper. The advantages of double sets of automatic integrity and reduce missing weather station are discussed, which can effectively ensure the data rate. The results show that temperature, relative humidity and air pressure have high consistent rate,low gross error rate and out-of-tolerance rate. But the 2 minute average wind speed and 0 cm ground temperature have larger difference with high gross error rate and out-of-tolerance rate. The data evaluation shows that the abnormal data can be found through analyzing the moving average of change characteristics. And the double automatic weather station will provide good foundation for accurate and reliable observation data.
