Abstract

Based on long-term study in the Kara Sea basin (11 expeditions in 2007–2022), we, for the first time, statistically generalize atmospheric aerosol characteristics: the volume concentrations of submicron and coarse aerosol (V_f and V_с), the black carbon concentrations (еВС), and the spectral aerosol optical depth (AOD) of the atmosphere. High concentrations of submicron and absorbing (eBC) aerosol are pronounced in the average spatial distribution in the southwestern part of the Kara Sea, and they are minimal in the northern part. The difference in the average V_f and еВС between these regions is 30–60%. The average aerosol characteristics for the entire Kara Sea are: the atmospheric AOD (0.5 μm) is 0.043 with an Ångström exponent of 0.8, еВС = 22.8 ng/m³, V_f = 0.26 μm³/cm³, and V_с = 1.39 μm³/cm³. The average V_f and еВС over the Kara Sea are shown to be intermediate between the values for the Cape Baranov and the Barents Sea.

喀拉海盆地大气气溶胶的空间分布和平均特征

摘要基于对喀拉海盆地的长期研究（2007-2022年的11次考察），我们首次统计归纳了大气气溶胶特征：亚微米气溶胶和粗气溶胶的体积浓度（Vf和Vс）、黑碳浓度（еВС）以及大气的光谱气溶胶光学深度（AOD）。在喀拉海西南部的平均空间分布中，亚微米和吸收（eBC）气溶胶浓度较高，而在北部则很小。这些地区的平均 Vf 和 еВС 差值为 30-60%。整个喀拉海的平均气溶胶特征为：大气 AOD（0.5 μm）为 0.043，Ångström 指数为 0.8，еВС = 22.8 ng/m3，Vf = 0.26 μm3/cm3，Vс = 1.39 μm3/cm3。卡拉海的平均 Vf 和 еВС 介于巴拉诺夫角和巴伦支海的数值之间。
