Abstract

The spatiotemporal variability of carbon monoxide (CO) during the atmospheric blocking event over European Russia in summer of 2010 is studied using the CO measurements from satellite Atmospheric Infrared Sounder (AIRS) instrument. Total column CO data from AIRS are compared with those from the ground-based spectrometer operated at Zvenigorod Scientific Station of A.M. Obukhov Institute of Atmospheric Physics. The peculiarities of CO field evolution conditioned by the regional atmospheric circulation associated with the omega block in the presence of severe wildfires are revealed.
