Special Issue Information

Dear colleagues,

The concentrations of pollutants and greenhouse gases in the atmosphere are determined by their sources and sinks. Sources include direct emissions and chemical productions, and sinks include chemical loss and deposition processes. Some of the air pollutants, for example, reactive nitrogen and ozone, result in negative effects on ecosystem health and influence soil carbon storage when removed from the atmosphere by deposition processes. Thus, the quantification of sources and sinks of air pollutants and greenhouse gases is crucial for preparing emission control strategies for mitigating air pollution, ecological impact, and climate change.

The “sources and sinks of air pollutants and greenhouse gas” is a broad scientific scope that includes impacts from anthropogenic activities, chemical reactions, climate changes, and the feedback between the atmospheric components and the ecosystem. Atmosphere invites scientists and researchers to contribute to this Special Issue by submitting manuscripts. The scientific topics include but are not limited to the following:

  1. Bottom-up and top-down estimation of the emissions from anthropogenic and natural sources;
  2. Quantification of the atmospheric deposition through observations and atmospheric chemistry models;
  3. The influences of reactive chemical species on the budget of greenhouse gases;
  4. Drivers of atmosphere–biosphere interaction of chemical species;
  5. The influences of climate changes on the sources and sinks of air pollutants and greenhouse gases.

The accurate estimation of ammonia emission is essential for quantifying secondary inorganic aerosol formation and reactive nitrogen deposition. During the last decades, both fertilizer type and the total amount of nitrogen fertilizer in China have changed, while the resulting changes in ammonia emissions and their spatio-temporal variations are unclear. In this study, we compile a long-term (2005–2020) high-resolution ammonia emission inventory for synthetic fertilizer in China with bottom-up method. We parameterized emissions factors (EFs) considering the impacts of soil properties, method of fertilizer application, fertilizer type, crop type, ambient temperature and wind speed. Meanwhile, the monthly nitrogen fertilizer application is calculated by detailed information on crop-specific fertilizer application practices. For the spatial distribution, the ammonia emissions from fertilizer mostly concentrate in eastern and southwestern China, coincident with the high density of agriculture activity and population in these regions. For the seasonal variation, the ammonia emissions from fertilizer application peak in spring and summer because of dense fertilizer application and high ambient temperature. For the long-term trend, we estimate that the emissions from synthetic fertilizer increased from 5.38 Tg in 2005 to 5.53 Tg in 2008 and remained nearly unchanged during 2008–2012, then decreased to 3.96 Tg in 2020. Urea, ammonium bicarbonate (ABC) and nitrogenous compound fertilizer are major fertilizer types used in China. Despite the increased use of nitrogen fertilizer, ammonia emissions remained stable throughout 2008–2012 with the declined use of ABC. This stable period also reflects ammonia emission increases in western China, offsetting the decreases in eastern China. Furthermore, our emission inventory provides a monthly estimation at a spatial resolution of 0.1 degrees, which can be applied to global and regional atmospheric chemistry model simulations.
