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.

拟议的研究将解决高纬度地区降水测量仪测量的偏差。 由于低温和降水，加上大风，高纬度地区的偏差误差可能超过100%。 这项研究将建立在广泛的实验基础上，特别是世界气象组织（气象组织）的固体降水测量相互比较项目，以评估降水测量的准确性，并对北极地区进行一致的偏差校正。 研究目标是为泛北极地区建立一个无偏见的降水数据库和气候学。 研究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。
