Estimate of latitudinal and longitudinal boundaries of aerosol regions in the East Atlantic

摘要

In 2004-2015, along the route of the Russian Antarctic Expeditions in the East Atlantic, we performed annual measurements of aerosol parameters: number concentrations of small (d = 0.4-1 μm) and large (d > 1 μm) particles, mass concentrations of aerosol and black carbon, atmospheric aerosol optical depth (AOD), and its fine- and coarse-mode components. The obtained data allowed us to reveal the regularities of latitudinal (with 5° step) distribution of aerosol parameters and create the prerequisites for their zoning. In the work, the latitudinal boundaries of the identified regions are estimated. To estimate the longitudinal boundaries of the aerosol regions, we employ multiyear (2002-2015) data of satellite (MODIS/Aqua&Terra) measurements of atmospheric AOD.
