摘要本文评估了印度次大陆10年（1997/98-2006/07）期间格网站数据、卫星数据和再分析产品的7种降水产品的季节（冬季、季风前、季风和季风后）表现。评估的降水产品有亚洲降水-高分辨率观测资料整合水资源评价（APHRODITE）、气候预测中心统一（CPC-uni）、全球降水气气学项目（GPCP）、热带降雨测量任务（TRMM）后实时研究产品（3B42-V6和3B42-V7）、气候预报系统再分析（CFSR）、以及欧洲中期天气预报中心（ECMWF）中期再分析（ERA-Interim）。采用了几种验证措施来评估数据的准确性。所有数据集都捕获了季节平均降水分布的大尺度特征，尽管p…
AbstractThis paper evaluates the seasonal (winter, premonsoon, monsoon, and postmonsoon) performance of seven precipitation products from three different sources: gridded station data, satellite-derived data, and reanalyses products over the Indian subcontinent for a period of 10 years (1997/98–2006/07). The evaluated precipitation products are the Asian Precipitation–Highly-Resolved Observational Data Integration Towards Evaluation of the Water Resources (APHRODITE), the Climate Prediction Center unified (CPC-uni), the Global Precipitation Climatology Project (GPCP), the Tropical Rainfall Measuring Mission (TRMM) post-real-time research products (3B42-V6 and 3B42-V7), the Climate Forecast System Reanalysis (CFSR), and the European Centre for Medium-Range Weather Forecasts (ECMWF) interim reanalysis (ERA-Interim). Several verification measures are employed to assess the accuracy of the data. All datasets capture the large-scale characteristics of the seasonal mean precipitation distribution, albeit with p...
