Assessment of the Spatial Structure of Black Carbon Concentrations in the Near-Surface Arctic Atmosphere

The results of the research are numerical estimates average fields black carbon mass concentration in surface layer atmosphere Arctic region obtained using numeric technology referred to as fluid location (FLA). modelling has been based on measurements concentrations near-surface during two cruises Professor Multanovskiy (28 July–7 September 2019) and Akademik Mstislav Keldysh (31 July–24 August 2020) vessels. These have supplemented by at stationary monitoring points located Spitsbergen Severnaya Zemlya archipelagoes. simulation summertime demonstrates that areas increased were observed over Northern Europe and, 2019, also Laptev Sea basin. spatial distribution qualitatively agreed with same data derived from second Modern-Era Retrospective analysis for Research Applications (MERRA-2) but showed quantitative differences. values zones follows: 85.3 ng/m3 (2019) 53.6 (2020) reconstructed FLA technology; 261.69 131.8 MERRA-2 data.
