Analysis of Spatial-Temporal Variability of Tropospheric NO_2 Column over Moscow Megapolis Using OMI Spectrometer (Aura Satellite) Data

摘要

Results of analysis of nitrogen dioxide (NO_2) tropospheric column amount over Moscow and its suburbs during the period from 2004 to 2009 are described. Spatial distributions of long-term mean NO_2 content and NO_2 contents in opposite phases of its weekly and seasonal cycles are presented. The maximum annual values of NO_2 reaching 8.3 × 10~(15) mol cm~(-2) were recorded east of the Moscow Ring Highway (MRH) between Balashikha and Lyubertsy, while the minimum values were recorded over Zelenograd (less than 5 × 10~(15) mol cm~(-2)).
