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

拟议的研究将解决高纬度地区降水计测量中的偏差。由于低温和降水，再加上大风，高纬度地区的偏置误差可能超过100%。这项研究将建立在一个广泛的实验基础上，特别是世界气象组织（WMO）固体降水测量比对项目，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。研究目标是建立一个无偏差的泛北极降水数据库和气候学。结果将提高我们对降水的时空变化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.
