Uncertainties in Arctic Precipitation

In our study, we aim to understand and compare precipitation datasets and discrepancies associated with them. We divide our datasets into three classes-raw data (data that have only been preprocessed to minimum quality control);corrected products (data that have been adjusted by their respective authors); finally, a reanalysis dataset (a combination of observed data and model output).本研究旨在理解并对比各类降水数据集及其相关的偏差。我们将研究涵盖的数据集划分为三类：其一为原始数据（Raw data），即仅完成最低质量控制预处理的数据；其二为订正产品（Corrected products），即经其原作者调整后的数据；其三为再分析数据集（Reanalysis dataset），即观测数据与数值模式输出的结合产物。
