Aerosols play a key role in the radiation balance of the atmosphere. Here, we present evidence that the European boreal region is a substantial source of both aerosol mass and aerosol number. The investigation supplies a straightforward relation between emissions of monoterpenes and gas-to-particle formation over regions substantially lacking in anthropogenic aerosol sources. Our results show that the forest provides an aerosol population of 1000 to 2000 particles of climatically active sizes per cubic centimeter during the late spring to early fall period. This has important implications for radiation budget estimates and relevancy for the evaluation of feedback loops believed to determine our future climate.
气溶胶在大气辐射平衡中起着关键作用。在此，我们提供证据表明欧洲北方地区是气溶胶质量和气溶胶数量的重要来源。该调查提供了在基本缺乏人为气溶胶源的地区，单萜排放与气体到颗粒形成之间的直接关系。我们的结果表明，在春末至初秋期间，森林每立方厘米提供1000至2000个具有气候活性尺寸的气溶胶颗粒。这对辐射收支估计具有重要意义，并且对于评估被认为决定我们未来气候的反馈回路具有相关性。
