Time and latitude dependence of the solar wind mass flux: updated SOHO/SWAN data analysis for the complete Solar Cycle 23

Abstract : We present an updated analysis of SOHO/SWAN data using the latest absolute calibration of the instrument for the complete Solar Cycle 23 period and onset of Solar Cycle 24. We calculate the total interplanetary hydrogen ionization rates as a function of latitude and time by fitting a hot model to the calibrated SWAN maps. We derive the solar wind mass flux and provide a preliminary comparison with ecliptic in-situ measurements from WIND. Future projects include a complete latitudinal comparison to the Ulysses data during the north and south polar passes of the instrument.
