摘要
GPM降水计划是继TRMM之后新一代全球卫星降水产品,其核心观测平台已于2014年2月28日发射,卫星群目前由10颗卫星组成,未来还有可能继续扩充。但目前国内还缺少专门介绍GPM计划及其产品的最新文章。新一代GPM降水产品分为4级,与以往的卫星降水产品相比具有更高的精度、更大的覆盖范围、更高时空分辨率,能够提供全球范围基于微波的3h以内以及基于微波红外IMERG算法的30min的雨雪数据产品,有利于促进水文、气象、农业和灾害等学科的研究和应用。与着重观测热带亚热带地区降水的TRMM相比,GPM能够更加精确地捕捉微量降水(<0.5mm·h-1)和固态降水,这两种类型降水的观测对中高纬度地区和高原地区具有重要意义。对GPM计划的核心观测平台、算法产品、地面验证和应用前景等进行了阐述,有利于GPM产品在国内的应用和推广。
