A database of atmospheric nitrogen concentration and deposition from the nationwide monitoring network in China

Here we present an explicit dataset for inorganic N concentrations and deposition for the period 2010-2015 in China, compiled from the nationwide deposition monitoring network. The dataset comprises information from 32 monitoring sites on concentrations and bulk deposition (wet plus part of dry deposition) fluxes of NH₄⁺-N and NO₃^--N, air concentrations and dry deposition fluxes of the major Nr species NH₃, NO₂, HNO₃, and particulate NH₄⁺ and NO₃^-. This unique database is available inter alia to advance understanding of the spatial patterns of inorganic N concentrations and deposition in China and its associated effects, constrain primary Nr (e.g., NH₃, NO<i>_x</i>) emission inventories, and validate outputs of atmospheric chemistry and transport models. <br>

本研究发布了一套基于全国沉降监测网络汇编的中国2010-2015年无机氮浓度与沉降详实数据集。
该数据集涵盖全国32个监测站点的相关数据，包括铵态氮（NH4+-N）与硝态氮（NO3--N）的浓度及混合沉降（湿沉降与部分干沉降之和）通量，同时包含主要活性氮（Nr）物种——氨气（NH3）、二氧化氮（NO2）、硝酸（HNO3）以及颗粒态铵（NH4+）与硝态氮（NO3-）的大气浓度与干沉降通量。
该数据库可用于诸多研究场景，尤其包括：深化对中国无机氮浓度与沉降的空间格局及其相关影响的认知，校准活性氮（Nr）一次排放清单（如氨气（NH3）、氮氧化物（NOx）），并验证大气化学与传输模型的模拟结果。
