A dataset of ≥10℃ accumulated temperature of field stations in Chinese typical ecosystems from 2001 to 2015

They are usually characterized by temperature and accumulated temperature. The study adopts 10°C as a threshold because this is the threshold temperature for the growth of thermophilic plants, a temperature at which chimonophilous crops grow rapidly and perennial crops accelerate its accumulation of dry matter.

Agricultural departments and institutions often use the ≥10℃ accumulated temperature and its corresponding duration to measure the agro-climatic production potential of a region, which importantly guides the introduction and cultivation system reform. Based on the average daily temperature automatically observed by the Chinese Ecosystem Research Network (CERN), we used the 5-day moving average method to build a dataset of ≥10℃ accumulated temperature at field stations of typical Chinese ecosystems from 2001 to 2015.
