【 摘 要 】

Changes in the composition of the atmosphere associated with the atmospheric blocking events were analyzed using the measurements of ozone, water vapor, methane, formaldehyde, carbon monoxide, nitrogen dioxide, as well as aerosol optical characteristics from the satellite instruments OMI, MLS, AIRS, MODIS and MOPITT as well as ground-based, balloon and NCEP/NCAR reanalysis data. The changes in atmospheric composition associated with pyrogenic, biogenic and soil emissions of aerosol and gas constituents as well as the changes due to the regional peculiarities of the large-scale atmospheric dynamics are discussed.
