Deposition 2020: NOy

The data sets/maps contain information on the annual amount of NOy (the part of nitrogen deposition resulting from NOx emissions) deposited on plants, soil and water from the air. The deposition is located in a grid where the weight of the total annual deposition is calculated for each square of the grid. The data sets are the result of model calculations using the DEHM model carried out by DCE, Aarhus University in connection with the subprogramme for air under NOVANA.本数据集/地图包含了通过大气沉降于植物、土壤与水体中的年总氧化态氮（NOy，即由氮氧化物（NOx）排放产生的氮沉降组分）沉降量相关信息。该沉降数据以网格化空间框架组织，针对每个网格单元计算得到年度总沉降量的权重占比。本数据集为奥胡斯大学DCE中心配合NOVANA框架下大气子项目，运用DEHM模型开展模拟计算所得到的成果。
