Abstract  Large-scale, long-term historical data sets of land surface water and energy fluxes can help us understand global and regional environmental system and interactions with human activities, especially climate change in the distant future. In the past two decades, the climate change in northwest China, especially in Xinjiang was characterized by increasing precipitation, rising air temperature, melting glacier, increasing runoff, enlarging lake area, etc, which illuminated that there were significant changes in the climatic and hydrological processes, but the lack of long-term and large-scale historical records of the land surface water and energy budgets made us not be sure about the characteristics of water and energy process. Modeling can provide consistent fields of land surface fluxes and states. In this paper we describes the construction process of 3-hour, 0.5°×0.5° resolution forcing dataset of 45-year meteorological data for whole Xinjiang that can be used to drive land surface models. The data sets include precipitation, air temperature, wind speed, specific humidity, air pressure and surface downward solar radiation. The final product can provide a long-term, consistent dataset of near-surface meteorological variables that can be used to drive terrestrial hydrological and ecological process models and lay a foundation for the study of monthly, seasonal, annual and decadal changes of water and energy processes and for the evaluation of coupled models and other land surface prediction schemes.
