Using the ASPERA-4 instrument onboard Venus Express the change in the atmospheric boundary layers are investigated. Using the instrument when it is in the apoapsis period of the polar orbit allows pure Solar Wind measurements to be taken. Composition ratios are determined thus identifying periods of fast and slow solar wind. This is then applied to ion maps of the Venusian atmosphere to determine the response after noise calibration methods. The Species reactions to the differing Solar Wind are also used to investigate the inner boundary movements.
