This dataset is the monthly average sampling data of C13 isotope bottles in carbon dioxide at the Global Atmospheric Background Observatory in Waliguan, China from 1990 to 2012. The Valiguan Atmospheric Background Reference Observatory in China was founded in 1994 and is located on the Qinghai Tibet Plateau at an altitude of 3810 meters. It is the highest atmospheric background reference monitoring station in the world and the first atmospheric background reference monitoring station located in the hinterland of a continent. Its establishment fills the gap of the Global Atmosphere Watch(GAW) in the Eurasian continent
The Waliguan Atmospheric Background Reference Observatory is jointly invested and constructed by the Chinese government and the Global Environment Facility, and is operated and managed by the China Meteorological Administration. Comprehensive atmospheric background baseline monitoring mainly focused on greenhouse gas and atmospheric ozone monitoring; Due to the fact that carbon, hydrogen, oxygen, and nitrogen are the most common elements in organic compounds and living organisms, using non radioactive 13C as a tracer atom will be more convenient for studying organic and biochemical reactions, and therefore have been widely used
