| Zusammenfassung |
| With the potential of a future hydrogen fuel economy looming it has become apparent that our understanding of the current processes governing the H2 cycle is limited. Thus any negative effects resulting from increasing atmospheric H2 are somewhat ambiguous. To further understand the cycling of H2 and CO in the atmosphere we present a 12 month times series of atmospheric measurements of H2 and CO made at Weybourne Atmospheric Observatory (UK) as part of the EU funded EuroHydros project. We discuss various diurnal and seasonal features in H2 and CO and compare these with both chemical and physical parameters routinely measured at Weybourne Atmospheric Observatory. In particular we emphasise observed nocturnal decreases in H2 associated with nocturnal inversion events detected using SODAR technology. Using this we estimate the dry deposition velocity of H2 and CO to the soil, a substantial sink term in both H2 and CO budgets. An increased understanding of this soil sink of H2 and CO will aid in improving its application in global models. |
