Description
Like in any data sets, wave intensity measurements are often affected by background issues. Due to the properties of chorus emissions, it is expected to have a stronger impact on lower and upper chorus band than on plasmasheric hiss or lightning whistlers emissions. In this study we have analysed background level for each wave band available in the ONERA database (DE1/PWI, CRRES/PWE, POLAR/PWI, CLUSTER1/STAFF-SA, Double Star1/STAFF, Themis-A/FFT, Themis-D/FFT and Themis-E/FFT). Then distribution of wave intensity in the inner magnetosphere have been deduced for each emissions (Plasmaspheric hiss, lightning whislers, lower chorus and upper chorus) and each data sets. Finally the impact of background measurements on average global maps of wave intensity will be discussed.
