Investigation of in-take mechanism of NO3- by solid precipitation particle in cloud

为了调查和核实固体降水过程的长距离输送所提供的化学成分，在NY-Aelesund进行了一些观测，以收集固体降水颗粒、气溶胶颗粒和气体，作为一个充分远离源头的地区。北极海冰覆盖区的西北风吹来的雪粒中SO42-和NO3-的含量，比湾流北端开阔海域的东南风吹来的雪粒要少，没有覆盖的雪粒含有更多的硝酸根。值得注意的是，这些观测结果与一些实验室实验和最近对极地地区新鲜雪和环境大气的观测结果是一致的。

To investigate and verify the chemical components provided by long range transportation with solid precipitation processes, some observations were carried out at Ny-Aelesund as a sufficient remote area from sources by collections of solid precipitation particles, aerosol particles and gases. Snow particles without riming were observed to contain Less and more of SO42- and NO3-, respectively, brought by northwesterly wind from arctic sea ice covering fields than those with riming by southeasterly wind from open sea area in the north end of Gulf stream. It may be remarked that these observational results are coincident with those of some laboratory experiments and most recent observations of fresh snow and environmental atmosphere in polar regions.
