2020-2021中国典型生态系统大气氮湿沉降数据集

本数据集基于2020-2021年对中国60个典型生态系统（森林、草地、荒漠、农田和湿地）开展规范系统的雨水样品收集，储存，运输和室内分析测试工作，生成了一套2020-2021中国60个典型生态系统大气氮湿沉降数据集。数据类型为Excel表，数据以站点为单元，时间涉及2020和2021年的月，季，年尺度，包含NH4+, NO3- 两类氮湿沉降组分。表格字段包括：序号，通量站名，纬度，经度，生态系统类型，1月，2月，3月，4月，5月，6月，7月，8月，9月，10月，11月，12月，春季，夏季，秋季，冬季，年值。季氮湿沉降通量是通过计算相应季节月份的加和得到的。春季为3,4,5月的氮湿沉降通量加和，夏季为6,7,8月的氮湿沉降通量加和，秋季为9,10,11月的氮湿沉降通量加和，冬季为12,1,2月的氮湿沉降通量加和，年值为1-12月的氮湿沉降通量加和。Excel共计4080条数据。所有数据可完全开放共享。

This dataset is generated from standardized, systematic rainwater sample collection, storage, transportation, and laboratory analysis and testing performed on 60 typical ecosystems (forests, grasslands, deserts, farmlands, and wetlands) across China between 2020 and 2021, resulting in the *2020–2021 Atmospheric Nitrogen Wet Deposition Dataset for 60 Typical Ecosystems in China*. The data are stored in Excel format, organized by monitoring station, with temporal coverage including monthly, seasonal, and annual scales for the years 2020 and 2021, and contains two nitrogen wet deposition components: NH4+ and NO3-. The table columns are as follows: Serial Number, Flux Monitoring Station Name, Latitude, Longitude, Ecosystem Type, January, February, March, April, May, June, July, August, September, October, November, December, Spring, Summer, Autumn, Winter, and Annual Value. Seasonal nitrogen wet deposition fluxes are calculated as the sum of the fluxes of the months within the corresponding season: Spring is the sum of fluxes from March, April, and May; Summer is the sum from June, July, and August; Autumn is the sum from September, October, and November; Winter is the sum from December, January, and February; and the Annual Value is the total sum of fluxes from January through December. There are 4080 total data entries in this Excel file. All data is fully open and freely shareable.
