The Atmospheric Ionization Module OSnabrück (AIMOS) calculates a global 3D ionization profile based on data from the NOAA GOES and POES satellites that can be used e.g. in climate models. Due to a discontinuation of both input data sets the model was restricted to the years 2001 to 2010. In this work we will describe how the model has been extended to 2016. During the extension a couple of problems in the satellite data became obvious that may also impact other studies based on GOES or POES data, e.g. the new GOES satellites have different energy ranges even though the instument is identical to the older ones (e.g. P7 old 165.–500.MeV, P7 new 110.–900.MeV). Finally it turned out that the energy ranges are simply not known or at least subject of severe uncertainties, which is good to know as this satellite data is widely used for 20 years now. We will present our attempt to overcome this limitation by recalculating the energy thresholds based on the shifted center energy with variing steepness of the flux spectrum. In case that newer satellite data shows significant flux differences as e.g. in the magnetospheric energies, the impact on atmospheric ionization will be discussed.
