An aerostat-borne instrument and sampling method was developed to characterize air samples from area sources, such as emissions from open burning. The 10 kg battery-powered instrument system, termed "the Flyer", is lofted with a helium-filled aerostat of 4m nominal diameter and maneuvered by means of one or two tethers. The Flyer can be configured variously for continuous CO₂ monitoring, batch sampling of semi-volatile organic compounds (SVOCs), volatile organic compounds (VOCs), black carbon, metals, and PM by size. The samplers are controlled by a trigger circuit to avoid unnecessary dilution from background sampling when not within the source plume. The aerostat/Flyer method was demonstrated by sampling emissions from open burning (OB) and open detonation (OD) of military ordnance. A carbon balance approach was used to derive emission factors that showed excellent agreement with published values.
一种基于浮空器的仪器和采样方法被开发出来，用于对区域源（如露天燃烧排放）的空气样本进行特征分析。该 10 公斤重的、由电池供电的仪器系统被称为“Flyer”，使用充满氦气的 4 米标称直径的浮空器进行升空，并通过一根或两根系绳进行操纵。Flyer 可以通过各种配置进行连续 CO₂监测，对半挥发性有机化合物（SVOCs）、挥发性有机化合物（VOCs）、黑碳、金属和按大小分的颗粒物进行批量采样。采样器由触发电路控制，当不在源羽流范围内时，可避免因背景采样而造成不必要的稀释。浮空器/Flyer 方法已通过对露天燃烧（OB）和军事弹药露天爆炸（OD）排放的采样得到验证。采用碳平衡方法得出的排放因子与已发表的值吻合得很好。
