全球降水气候学中心（GPCC）最近开发了一种基于事件的天气降水观测系统测量误差日偏差校正方法，该方法已从区域应用转移到全球应用。利用现有的天气预报资料，对16个冬季月份的60多万个全球天气学资料进行了分析，从而将气温和露点温度与液态、固态和混合降水相态的可能分布联系起来。基于这些信息，天气降水观测可以在日分辨率上校正系统测量误差，这使得极端降水事件的估计更加可靠。(C)2001爱思唯尔科技有限公司版权所有。
A recently developed method for event-based daily bias-correction of synoptic precipitation observations regarding systematic measuring errors was transfered at the Global Precipitation Climatology Centre (GPCC) from regional to global applications. Using the reported present weather, an analysis based on more than 600 000 global synoptic data from 16 winter months was done, which made it possible to relate air temperature and dew point temperature to the probable distribution of liquid, solid and mixed precipitation phase. Based on this information, synoptic precipitation observations can be corrected regarding systematic measuring errors on a daily resolution, which makes the estimation of extreme precipitation events more reliable.
