我国气候资料均一性研究现状与展望
Climate Data Homogeneity Studies in China: Progresses and Prospects
中文摘要：
时空均一的气候资料是气象科研、业务和服务的基础。介绍了气候资料均一性的基本概念、涉及范围、主要原因以及解决非均一性问题的意义。在此基础上，阐述了国际上气候资料均一性研究的动态和技术发展历程，指出以高时空分辨率的均一化为标志的第二代气象数据产品研发趋势为气候资料均一性研究带来良好的发展机遇和严峻的挑战；结合对我国地面、高空和辐射三类气候资料均一性概况和相关研究现状的总结，分析了我国在相关领域研究的深度和广度上存在的差距和不足，以及当前需要解决的关键科学和技术问题。最后，就如何正确认识气候资料的均一性，如何深化我国气候资料均一性研究，加强气候数据产品研发，实现我国数据产品研发技术和管理水平上一个新台阶等提出了建议。

Abstract：
The homogenous climate data is the foundation of meteorological research, operation and services. This paper introduces the basic concept, the scope, main reasons of the data inhomogeneityand the importance to solve the problem in China. Firstly, we introduce the development history and the current progresses in the field of climate data homogenization, and point out that the development boom of the second generation data products, which is featured by the high temporal and spatial resolutions in meteorological data, will bring good opportunities and severe challenges to climate data homogenization studies; then, we summarize the related researches on three kinds of climate data (surface, radiosondes and radiation) and present the existing gaps and deficiencies in China on the depth and breadth of research in related fields, and point out the needs to solve the key problems in science and technology. Finally,we suggest how to correctly understand and deepen climate data homogenization studies, and how to strengthen the climate data product research and development, so that we may step forward a new stage of the climate data products development and of management level in China.
