大气中空气离子与aerosol particles的相互作用

The interaction between air ions and aerosol particles in the atmosphere

KL Aplin, RG Harrison

摘要:

带电粒子在大气中不断产生,自然电离和大气粒子之间的相互作用是复杂的。确定离子是否与粒子的形成有关,这在气候上是很重要的。大气离子浓度进行了调查,在这里在高时间分辨率,使用Gerdien离子分析仪在一个网站,同步气象测量也进行了。还用盖革计数器监测背景电离率,使来自天然放射性的离子产生与其他效应区分开来。在1Hz的测量提供了一些承诺,在建立离子成核爆发的大气电的影响,虽然其他气象因素的组合也被称为是显着的。因此,高时间分辨率的气象和离子测量对于推进对大气气溶胶行为的基本了解显然是必要的。

英文摘要:

Charged particles are continually generated in atmospheric air, and the interaction between natural ionisation and atmospheric particles is complicated. It is of some climatic importance to establish if ions are implicated in particle formation. Atmospheric ion concentrations have been investigated here at high temporal resolution, using Gerdien ion analysers at a site where synchronous meteorological measurements were also made. The background ionisation rate was also monitored with a Geiger counter, enabling ion production from natural radioactivity to be distinguished from other effects. Measurements at 1Hz offer some promise in establishing the atmospheric electrical influences in ionic nucleation bursts, although combinations of other meteorological factors are also known to be significant. High time resolution meteorological and ion measurements are therefore clearly necessary in advancing basic understanding in the behaviour of atmospheric aerosol.
