Atmospheric effects of energetic electron precipitation
We present the results of the analysis of data on precipitation of high-energy magnetospheric electrons into the atmosphere and their impact on the concentration of nitrogen oxide NO in the atmosphere at altitudes of 64–90 km. Series of data on precipitation recorded on balloons at the Apatity polar station (Murmansk oblast) in the period 2002–2012 and the results of NO measurements with the SCIAMACHY spectrometer (SCanning Imaging Absorption SpectroMeter for Atmospheric CHartographY) installed on board the European satellite ENVISAT were used. The response of variations in the concentration of nitrogen oxides to individual cases of precipitation of high-energy electrons and the average response to all events recorded in the atmosphere in 2002–2012 are considered.
