Development of Bias-Corrected Precipitation Database and Climatology for the Arctic Regions

这项拟议的研究将解决高纬度地区雨量计测量的偏差问题。由于气温和降水较低，再加上大风，高纬度地区的偏差可以超过100%。这项研究将建立在广泛的实验基础上，特别是在世界气象组织(WMO)固体降水测量国际比较项目的基础上，以评估降水测量的准确性，并对北极地区实施一致的偏差校正。这项研究的目标是为泛北极开发一个公正的降水数据库和气候学。结果将增进我们对降水量的时空变异性及其对北极地区淡水收支的贡献的理解。

The proposed research will address biases in precipitation gauge measurements from high latitudes. Because of low temperatures and precipitation, coupled with high winds, bias errors at high latitudes can exceed 100%. The research will build on an extensive experimental base, especially on the World Meteorological Organization (WMO) Solid Precipitation Measurement Intercomparison Project, to assess the accuracy of precipitation measurements and implement consistent bias corrections for arctic regions. The research goal is to develop an unbiased precipitation database and climatology for the pan-Arctic. Results will improve our understanding of the spatial and temporal variability in precipitation and its contribution to the freshwater budget of the arctic regions.
