飞机进气口将用于粒子微物理和化学测量的机载仪器与周围大气连接起来。这些入口可能会使测量产生偏差，因为它们具有增强或去除样品中某些粒度分数的潜力。飞机本身可能会干扰周围的空气流线，从而干扰粒子采样。此外，等动力学采样和采样线内的传输损耗可能导致采样的气溶胶与环境气溶胶不同。此外，由于可压缩性效应或传热，入口可能通过水和其他挥发性物质的蒸发而改变颗粒的组成和大小。2002年4月12日至13日，在德国莱比锡莱布尼茨对流层研究所（IfT）举行的一次国际研讨会上讨论了这些问题。这里总结了本次研讨会的讨论、结论和建议。
Aircraft inlets connect airborne instruments for particle microphysical and chemical measurements with the ambient atmosphere. These inlets may bias the measurements due to their potential to enhance or remove certain particle size fractions in the sample. The aircraft body itself may disturb the ambient air streamlines and, hence, the particle sampling. Also, anisokinetic sampling and transmission losses within the sampling lines may cause the sampled aerosol to differ from the ambient aerosol. In addition, inlets may change the particle composition and size through the evaporation of water and other volatile materials due to compressibility effects or heat transfer. These problems have been discussed at an international workshop that was held at the Leibniz-Institute for Tropospheric Research (IfT) in Leipzig, Germany, on 12–13 April 2002. The discussions, conclusions, and recommendations from this workshop are summarized here.
