China Inorganic Nitrogen deposition database1.0

The atmospheric IN deposition fluxes database consists of three files (Fig. 1). The ‘data file’ provides yearly data on the dry, wet and total IN deposition fluxes. Specifically, dry deposition is the sum of two forms, gaseous and particulate, including NO2，HNO3，NH3，NO3-，NH4+. Wet deposition, on the other hand, is the sum of both NO3--N and NH4+-N. The ‘readme file’ explains the description about the ‘data file’ and the units of all variables included. The ‘source file’ includes the full references used in the database, which comprise satellite data and precipitation data, etc.

该大气无机氮（Inorganic Nitrogen, IN）沉降通量数据库包含三个文件（见图1）。"数据文件"提供了干沉降、湿沉降及总无机氮沉降通量的年度数据。具体而言，干沉降为气态与颗粒态两种形态的总和，涵盖二氧化氮（NO₂）、硝酸（HNO₃）、氨（NH₃）、硝酸根离子（NO₃⁻）以及铵根离子（NH₄⁺）。而湿沉降则为硝酸根氮（NO₃⁻-N）与铵根氮（NH₄⁺-N）的总量之和。"说明文件"对"数据文件"的相关说明以及所包含的全部变量的单位进行了解释。"来源文件"收录了本数据库所使用的全部参考文献，其中涵盖卫星数据、降水数据等类型。
