摘要
针对选取103座测风塔资料,提出完整的质量控制方案,并基于JRA-55、CRA-40等再分析资料,对测风塔资料的数据质量及质控方案效果进行检验评估.结果表明:(1)大部分测风塔数据的缺测率、可疑率和错误率都较低,只有少数测风塔在某些观测高度处的缺测率、可疑率、错误率较高;(2)无论是温度还是U风,测风塔资料与JRA-55 再分析背景场资料的质控Observation-Minus-Background(简称OMB)结果都更接近0,这表明相对于CRA-40再分析资料,JRA-55再分析资料在近地面气象要素重现模拟上具有一定的优势;(3)对测风塔观测资料质量控制效果进行检验评估结果表明,质量控制后的温度和UV 风相对于再分析资料的偏差更接近 0,标准差减小.相较而言,质量控制后UV风偏差和标准差减小得更多,其应用效果较温度要素好.
Abstract
A complete set of quality control schemes is proposed for the selected data of 103 wind measurement towers.Based on the reanalysis data such as JRA-55 and CRA-40,the data quality of the wind measurement tower data and the effect of the quality control scheme are tested and evaluated.The results show that:(1)the missing rate,suspicious rate and error rate of most wind measurement towers are low,and only a few wind measurement towers have higher statistical value at some certain observation heights;(2)For both temperature and U-wind,the OMB results of wind measurement tower data and JRA-55 reanalysis background field data are closer to 0,which indicates that compared with CRA-40 reanalysis data,JRA-55 reanalysis data has certain advantages in the simulation of near-surface meteorological elements;(3)The test and evaluation results of the quality control effect of the observation data of the wind measurement tower show that the deviation of temperature and UV wind after quality control is closer to 0 value which is compared with the reanalysis data,and the standard deviation is reduced.In contrast,the UV wind deviation and standard deviation are reduced more after data quality control,and its application effect is better than the temperature element.
