A data set of soil water and heat dynamic obtained in the meteorological observational site of TYA from 2005 to 2014

Soil water and heat status not only plays an important role in crop growth and water-saving irrigation, but also in atmospheric circulation and climate change. High quality long-term field monitoring data is particularly valuable. Hunan Taoyuan Aro-ecosystem National Observation and Research Station represents the complex agricultural ecological area of the hills in the south of the Yangtze River, which is a traditional production base of grain, oil, pig, cotton, hemp and subtropical fruits in China. This area is rich in light, heat, water and biological resources, high in climate production potential and developed in complex agricultural management. This data set was obtained at the meteorological observational site of Hunan Taoyuan Aro-ecosystem National Observation and Research Station from 2005 to 2014. The setting, observation, collection and processing methods and quality control system of the sample plots were carried out in accordance with the uniform provisions of CERN. The data contents include soil volume water content dynamic, soil stratification temperature dynamic, soil heat flux data, as well as air temperature, rainfall and phase for air humidity data. In order to make better use of these data, this data set collates and processes the data on the basis of the data in the CERN warehouse and controls the data again. The data set is of great practical significance for the study of carbon cycle, soil heat storage, surface energy and water transport, crop growth, crop layout adjustment and agricultural production.
