10-11 October 2006HYMN kick-off Objectives Improve process models of land-biosphere-atmosphere exchange of the HYMN gases and provide global and regional estimates of their natural sources and sinks. Provision of multi-year global satellite data sets of CH4 and CO and long-term time series of CH4 and N2O at a range of observing stations. Provide advice on further optimization of monitoring networks for the HYMN gases. Quantify atmospheric loss of CH4 and H2 and the impact of changing anthropogenic and natural (climate-induced) emissions on regional OH trends and on current and future global CH4 and H2 levels. Quantify how the possible future change to a hydrogen economy will affect the H2 distribution and the distribution of CH4 and O3 through changes in emissions of H2 and pollutants (NOx, CO, VOCs). Evaluate simulations with a new coupled atmospheric chemistry- biosphere model for CH4, N2O and H2 by comparison with ground based and satellite observations on a global and regional scale. New estimates of the sources and sinks of CH4 and H2 including their temporal and spatial variability.
