Satellite-derived peculiarities of total ozone field under atmospheric blocking conditions over the European part of Russia in summer 2010

详细

Based on the AIRS satellite spectrometer data (the Aqua platform), the peculiarities are studied of the field of total ozone (TO) under prolonged blocking conditions over the European part of Russia in summer 2010. It is revealed that the spatial distribution of TO values during the period of blocking was characterized by negative TO anomalies (up to -37 DU on the first ten days of August) over the western and northern peripheries of the blocking anticyclone and by positive TO anomalies (up to 60 DU) over the troughs adj oinmg the anticyclone. Possible mechanisms of the formation of TO anomalies are discussed. The results are presented of the validation of TO measurements with the AIRS spectrometer in May-September 2010 obtained from the data of TO measurements with Brewer spectrophotometers at Kislovodsk and Obninsk stations of the global ozone network.
