Abstract

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.
