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

Here we present a 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, NOx) emission inventories, and validate outputs of atmospheric chemistry and transport models. <br>

本研究发布一套针对中国2010-2015年无机氮浓度与沉降的数据集，该数据集由全国沉降监测网络的观测数据汇编而成。该数据集涵盖32个监测站点的相关信息，包括铵态氮(NH4+-N)与硝态氮(NO3--N)的浓度及沉降总量（湿沉降加部分干沉降）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)以及颗粒物态铵(NH4+)与硝酸盐(NO3-)的大气浓度与干沉降通量。这套独特的数据库尤其可用于多项科研工作：增进对中国无机氮浓度与沉降的空间格局及其相关影响的理解，约束活性氮（Nr，如NH3、NOx）的初始排放清单，以及验证大气化学与传输模型的输出结果。
