Quality Control and Effect Evaluation of Wind Tower Data in China
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.
