Abstract: Atmospheric deposition is commonly considered as the most effective approach to removing various pollutants from the atmosphere. It is also one of the main sources of nutrient and heavy metal input into natural terrestrial ecosystems. A systematic observation network of atmospheric wet deposition is helpful to quantify the deposition flux and explore the spatial-temporal pattern and influencing factors of wet deposition, which provides background references for ecological assessment. Long-term in situ observation is one of the three basic tasks of the Chinese Ecosystem Research Network (CERN). In 2013, China Wet Deposition Observation Network (ChinaWD) was established based on CERN. ChinaWD has 54 observation sites now, whose scope covers the main ecosystem types of China. It focuses on China’s natural and agricultural ecosystems and has adopted a systematic observation index system, including nitrogen, phosphorus, acid, base cation and heavy metal deposition. This dataset contains wet nitrogen (N), phosphorus (P), and acid deposition from 41 sites across China in 2013. The dataset is helpful for the design of nutrient addition experiments and model simulation.
