Iodine monoxide in the MBL IO maxima during low tide & day time Fine particle bursts coninciding with IO maxima G. McFiggans, 2010. K. L. Furneaux, 2010. Anja.Schoenhardt@iup.physik.uni-bremen.de SOLAS-ESA-EGU conference Frascati, 29 Nov – 2 Dec 2011 4
Important questions and aspects Impact of gaseous iodine • Ozone destruction – what is the relevance? • Particle formation – what is the relative contribution? (cp. sulfate aerosol, sea salt aerosol, SOA etc) Main release pathways / connections of iodine to the biosphere From phytoplankton / different groups / inorganic sources Required information • Column amounts / volume mixing ratios of iodine compounds (IO, I 2, OIO, precursors) …globally and long term • Altitude profiles of iodine compounds Anja.Schoenhardt@iup.physik.uni-bremen.de SOLAS-ESA-EGU conference Frascati, 29 Nov – 2 Dec 2011 5
