摘要:
新一代卫星降水产品GPM在全球降雨观测精度上较TRMM有大幅提升,但在青藏高原地区的精度仍然不理想,而目前遥感降水数据校正缺乏对数据中降水量、雨天频率以及概率分布多重属性的综合考虑。本文根据19个典型站点2014—2017年的日降水数据,在分析GPM降水探测精度的基础上,采用线性缩放法(LS)、局部强度缩放法(LOCI)、Gamma分布映射法以及Gamma和LOCI结合的方法(Gamma-LOCI)对青藏高原GPM数据进行了偏差校正。结果表明:(1)GPM对青藏高原日降水事件探测能力总体上表现出从年降水量较少的西北部洪积平原区以及中部腹地向年降水更丰富的东部山地区和平原区转好的趋势,从日降水强度来看,存在对小雨事件(<2 mm)高估和对大雨事件(>10 mm)低估的现象;(2)经四种方法校正后,GPM与站点观测数据在各百分位点上的整体偏差均有不同程度的降低,Gamma分布映射对降水时间序列的概率分布进行调整,修正了降水量并保留了极值,使其在降水偏丰区域的应用效果优于LS和LOCI; 和LOCI结合后同时对降水数据中雨量、雨天频率和时间概率分布校正,其应用效果进一步改善了GPM日降水过程的精度,提高了与站点日降水序列的拟合度和匹配度。研究结果为GPM在青藏高原地区的准确应用提供参考的校正方法,为区域水文模拟、水资源管理研究奠定基础条件。
