Modeling the Junge Layer Formation in Northern Latitudes: Spatiotemporal Structure and Particle Composition
The study presents the results of 3D modeling of the spatiotemporal structure of the atmo- spheric distribution of gaseous pollutants and Junge layer particles carried out for the winter of 2002. The study presents the results of numerical simulation of their number concentration and mass concentration, spectral and vertical distribution, and variability of the content of water and sulfuric and nitric acids in the particles. The calculations reveal that the key factor determining the spatiotemporal structure of the Junge layer is the atmospheric distribution of temperature and relative humidity. Calculated and observed data on the Jungle layer are compared.
