Atmospheric nitrogen deposition in a typical agricultural-ecosystem of the central Sichuan Basin of China (2008–2013)

Abstract

As a crucial process of the nitrogen biogeochemical cycle, atmospheric nitrogen (N) deposition brings organic and inorganic nitrogen into the ecosystem in the form of dry and wet (rainfall) depositions. A most straightforward and effective way to reveal components and spatiotemporal pattern of the atmospheric nitrogen deposition and its influencing factors is to monitor the depositions in a region or typical ecosystem. As part of CERN and CNERN, Yanting Station is a fundamental, public-welfare platform for agricultural ecosystem experimentation and observation oriented towards the subtropical purple soil area of Sichuan Basin. The station has started its observation of dry and wet atmospheric deposition since 2008. This dataset includes the monthly average concentration and volume of wet nitrogen deposition in 2008-2013, and the monthly average rate, concentration, volume and rate of dry nitrogen deposition in 2011-2013. This dataset not only helps understand air pollution by reactive nitrogen, but also provides statistical support for assessing local input of environmental nutrients by nitrogen deposition and its impact on ecological environment.
