中国均匀历史气温(1951年-2004年)数据集1.0版包括大陆所有国家气象站的逐月和逐日地面观测资料中国。CHHT1.0的主要目标是建立一套同质化的观测气候数据集，以减少检测观测到的气候变化和可变性的不确定性。CHHT1.0版本涵盖了1951年至2004年两种格式，即2.5°×2.5°空间分辨率的站和格网，数据集是利用分布在中国大陆的731个国家气象站的日平均、最低和最高气温观测数据建立的。CHHT1.0质量控制从基本检查开始，包括检查量程和极限值，检查内部一致性，以及相互检查测量结果。CHHT1.0温度数据包括两个不同的数据集，即原始数据和同质性调整后的版本。
The China Homogenized Historical Temperature (CHHT) dataset (1951-2004) version 1.0 consists of monthly and daily surface observations from all national stations in mainland China. The primary objective of CHHT 1.0 is to build a set of homogenized observational climatic datasets to reduce uncertainty in the detection of observed climatic change and variability. CHHT version 1.0 covers the years 1951-2004 in two formats that are stations and grids with 2.5°×2.5° spatial resolution and dataset is developed by using observations of daily mean, minimum and maximum temperatures from a total of 731 national weather stations distributed throughout mainland China. CHHT 1.0 quality control starts with fundamental checks that include the checking of range and limiting values, checking the internal consistency and, checking the measurements against each other. The CHHT 1.0 temperature data include two different datasets that are the original data and a homogeneity-adjusted version.
