2015年秋天，印度尼西亚数千平方公里的森林和泥炭地起火。在火灾排放的主要物质中，氨 (NH3) 与空气质量特别相关。在此，我们使用 2008-2015 年卫星测量数据得出受影响地区的每日和总 NH3 排放通量。 2015 年的火灾估计排放了 1.4–8.2 Tg 的 NH3（最大值为 0.06–0.33 Tg d−1）。按年计算，2015 年的 NH3 排放量比前 7 年增加了 2-3 倍。我们推导出泥炭土的 NH3 排放因子，发现该因子比 GFASv1.2 排放清单中使用的排放因子低 2.5-8 倍，但与其他近期研究报告的结果非常一致。最后，我们估计 2015 年的火灾消耗了 3.28 × 109 m3 泥炭土，相当于平均燃烧深度为 39 厘米。
In the autumn of 2015, thousands of square kilometers of forest and peatlands in Indonesia went up in flames. Among the primary species emitted by fires, ammonia (NH3) is of special relevance for air quality. Here we derive daily and total NH3 emission fluxes over the affected area using satellite measurements for the years 2008–2015. The 2015 fires emitted an estimated 1.4–8.2 Tg of NH3 (with a maximum of 0.06–0.33 Tg d−1). On an annual basis, the 2015 NH3 emissions are a factor 2–3 larger than in the previous 7 years. We derive NH3 emission factors for peat soils, which are found to be 2.5–8 times lower than those used in the GFASv1.2 emission inventory but in excellent agreement with those reported in other recent studies. Finally, we estimate that 3.28 × 109 m3 peat soil was consumed during these 2015 fires, corresponding to an average burn depth of 39 cm.
