CH$_{3}$OH is produced mainly from biogenic sources but also from dead plant matter and biomass burning \cite{Macdonald1993,Warneke1999,Holzinger1999}. Globally, the main sink of CH$_{3}$OH is oxidation by OH, however, the ocean provides a significant sink near Australasia. It has an atmospheric lifetime ranging from a few days in the boundary layer to a few weeks in the upper troposphere, making it an appropriate indicator for both local and transported sources \cite{Jacob2005,Heikes2002,Tie2003,Millet2008}. \textcolour{red}{A diurnal cycle has been noted by Holzinger et al. [2001] which varies during the winter and summer.}
