Global Atmosphere Reanalysis Datasets:Current Status and Recent Advances

导出

摘要在过去十多年,利用资料同化技术再分析过去的气象观测资料,重建高时空分辨率的格点历史气候数据集取得了长足发展。再分析资料的问世为人们深入了解大气运动的方式、认识不同时空尺度内气候变化和变率提供了强有力的、甚至不可替代的研究工具。就当前国际上一些主要的全球大气再分析资料研究计划及其产品的概况、再分析资料在大气科学及其相关研究领域中的应用、再分析资料的评估及其在气候变化研究中存在的一些主要质量问题做了回顾与介绍,并就未来大气再分析资料研究计划的一些发展趋势予以展望。 During the last decades, the reanalysis of past meteorological observations using modern data assimilation technique and the restructuring of the long-term and consistent gridded data products have made great progress. Such datasets provide us with the most primary research tools to identify the state and evolution of atmosphere, and understand the climate change and variability at different spatial-temporal scales. In this paper, the current research status and advances in the global reanalysis datasets including some of international global atmos- phere reanalysis projects and the corresponding reanalyzed products, the important applications of reanalyzed products in some research fields of the atmospheric science, the validation and evaluation of the reanalysis datasets, and some quality problems represented by the reanalyzed products in climate change studies are systematically reviewed. Moreover, the prospects of the studies of atmospheric reanalysis in the future are also discussed in this paper.
